I would to display the Simulink workspace in a MATLAB GUI window. This is
cosmetic as I know well that Simulink operates fine without this addition.
However, I have no idea how to have a space in a GUI where the Simulink
workspace can be displayed. Effectively, the GUI would form a thick frame
around the Simulink workspace. Please let me know how what commands can be used to create the workspace window.
Also, is it possible to have a place to store a reservoir of blocks, similar to the Simulink
library, in this GUI.
MATLAB GUIs and the Simulink editor rely on incompatible technology. You will not be able to embed the Simulink editor into a MATLAB GUI. What requirement do you have for Simulink modeling that isn’t met by the editor? There already exist many ways to customize the Simulink environment.
Doug is right about the Simulink editor, but you do have some freedom to put your own reservoir of blocks into the Simulink library browser. There is a section in the doc that describes how to do this.

how can I export an image of the area of the plot by code?
I'm using Netlogo 5.0.5.
I'm tring to reproduce the comand "copy image" of menu right-button of the mouse in the area-plot in tag "Interface".
There is no primitive to export a plot as an image in NetLogo, which is admittedly a hole in the language. It would be fairly simple to write an extension to do that, but as far as I know, none exists.
That leaves you with two alternatives:
Use export-plot, which will give you a CSV file, and recreate your plot using some other tool (e.g., Gnuplot). This is more work, but it has the advantage of giving you better quality output in the end, NetLogo plots being kind of bitmappy anyway...
Use export-interface to export the whole NetLogo interface tab as an image, and then crop the resulting picture to keep only your plot. If you use a command-line tool like ImageMagick, this can be fully automated.
In both cases, you could try calling the external program that you choose directly from NetLogo by using the Shell extension.
I want to design a 3D human hand and control it via signal generated from my Arduino kit. I designed a 3D hand in Blender but how to give the signal generated from Arduino to add life into it. Which tool I should use.
For example I have designed an arbitrary frequency generator. And I want at a particular frequency the Hand will mimic Pinching, or to Fist. Which tool I can use to use the generated signal as input to a Programming interface and output of the Program as a Animated 3D hand.
Please help guys......
Thanks in Advance.
Python would seem the obvious solution to this, as it can interface directly with Blender.
I'm not sure how your controller works with frequencies, but chances are there's a library or a way to handle it in python.
I would suggest looking at this forum post to learn how to set up the animation you want via python script.
Python can then be used to render a series of images (of the hand) like this:
for i in range(last_frame):
bpy.ops.anim.change_frame(frame = i)
bpy.data.scenes['Scene'].render.filepath = '/home/user/Pictures/frame%d.jpg'%i
bpy.ops.render.render()
I'm working on a small image processing project in MATLAB. I have worked with MATLAB before, but never created a GUI. The GUI I want to create could be pretty advanced, so I need some hints on how to get started.
The purpose of the GUI would be to load an image and have it shown to the user. The user then has to click on two points in the image, of which the coordinates are stored (in pixels) in a variable. If possible, a colored dot is shown where the user has clicked. After the user finished with the current image, he can load a next one.
I have some experience with Java, and I think this wouldn't be too hard in Swing. But MATLAB seems like not having the purpose of creating such an advanced GUI. However, the whole project until now is in MATLAB, so it would be nice if I could manage to do it. Any help? Hints? Things I should look at?
Thanks a lot.
This is not a very complex task to be done in MATLAB.
For simple instructions about adding a picture to a GUI, take a look at this post:
http://blogs.mathworks.com/pick/2007/10/16/matlab-basics-setting-a-background-image-for-a-gui/
For instructions on various interactions between GUI axes and the mouse pointer, check this video (keep in mind that your picture in the GUI lies within normal MATLAB axes):
http://blogs.mathworks.com/pick/2008/05/27/advanced-matlab-capture-mouse-movement/
In general, Doug's tutorial videos are great for MATLAB beginners, and I'd advise you to take a look at more of them.
Does anyone knows about any editor allowing to visually design a form (by form I do not mean DFM or Delphi form, but a "paper form", like those pre-printed forms that you fill with some info) and that generates pascal commands to draw that form in a Printer (or Image) canvas?
What I want is an easy way to draw/design this form visually, composed just by lines and text, and a way to convert this to Pascal commands that when run, will draw that form in a Canvas (Image or Printer), respecting the original layout and scale, doesn't matter the Canvas DPI where it is being drawn.
Update: Maybe I wasn't clear enough about what I need and why I need it. I developed an Open Source component called TFreeBoleto (freeboleto.sf.net). It is used to generate and print bank billets (a common method for billing people in Brazil). Right now, the component uses a TBitmap image containing the "billet" mask, and TextOut methods for the dynamic areas (ie: billet number, customer name, etc). It is fine when looked in the screen, but some people complains that the quality of the printed image is not good. The component uses a BltTBitmapAsDib procedure to maximize the quality of printing, but some people still think it is not good enough. So, my idea was to avoid using a bitmap image as the form layout, and draw everything direct in the canvas (both form and printer). Check here for a sample of what a bank billet looks like.
Of course ReportBuilder and/or FastReport could solve the problem, but they are not free, so I cannot include it in the component. I need "native" solution that any standard Delphi install would be able to compile.
You might get what you want out of the Fast Reports Report Designer which is a commercial reporting system for Delphi. Remember that a report is just a page. That page can be shown on the screen or printed on the printer.
You also might find that something like TRichView helps you.
Whether using TRichView in particular or not, I would look into using HTML to do what you want. I would use HTML+CSS to do both a screen and printer layout, that can also be viewed on the web. For simple text layout plus text boxes I think even bare HTML and HTML tables might be sufficient. To visually design simple text pages, using a Delphi application, I would use TRichView.
In both cases, you would be creating documents, not code. To create code that creates a page, without using any document system, would be very difficult indeed, and I am not sure what you would really do with that code, since you would need a compiler or interpreter to convert that code into something that you could use. Please clarify what you mean by "creating code", and what syntax you would want that code to be using. If HTML is code in your definition of "code" then maybe HTML is the best kind of "code" for your problem.
I do my form-work with WPTools. It is also a commercial product. The core is a very good wordprocessor and form-designer. The engine can render text and forms to any canvas (screen, printer, also create pdf) and is highly flexible. Output is mainly rtf and html.
I also see no advantage in creating pascal code to redraw the form. What you need, i think, is a good WYSIWYG-editor which creates a document that fits your needs.
Check out ReportBuilder # http://www.digital-metaphors.com/
It is a commercial reporting tool for Delphi - around a long time, very high quality, with all native Delphi source code packaged with it. I am using it for an important commercial project right now and I recommend it highly (I'm not working for them.) I've used MANY Delphi reporting tools over the years and this one is the best IMO.
RBuilder also has extensive support for paper form emulation see:
http://www.digital-metaphors.com/products/report_design/form_emulation.html
I haven't worked with that feature, but you can download a full-featured demo and try it.
Yoy can use Adobe Acrobat (full version) to create forms.
Then you can use free Acrobat Reader to display and print forms or other COM object in your application.
I think it is best solution for you.
PS
All tools for reports that are included in Delphi are free for you to design form and are free to distribute if user only preview and print already designed reports.
The same is valid for Adobe Acrobat (you may distribute forms) but you have added that you need to print form and some text over form. Maybe it is easier if you use reports but it is possible to do the same using PDF.
Most report engines are not open source but are free to distribute. There is many components for creating PDF - paid (one time), free, as well as open source.
PPS
I have read your updete for second time. Since you are using TBitmap and you can to TextOut so: You can use TMetafile. There is many editors for metafiles and it is free to distribute metafiles.
This open source fractal program Fraqtive, which uses Qt, has a really cool little gradient editor for coloring your fractals:
http://fraqtive.mimec.org/node/34
Does anyone know of any nice gradient editing interfaces that use wxWidget/wxPython?
I wrote one for a fractal program I wrote in wxWidgets; I've been meaning to wrap it up nice and release on wxCode when I had time.
This is inspired by photoshop's editor, so it may not be exactly what you're looking for.
The code for it is hosted here:
http://github.com/ecordell/chaostools/tree/master/src/
And the relevant files are: gradient.h, gradient.cpp, gradientdlg.h, gradientdlg.cpp
The wxGradientDialog object works just like any other dialog, and returns a wxGradient object, which uses a lerp to create the gradients from the color stops.
Try the PyColourChooser or the CubeColourDialog
