Unable to Write Inline Aggregate function in Matlab.
X1, X2 are array variables. And mb and nb are size of BUS DATA.
V is the voltage function, delta is the angle.
% objf=inline('sum(V(mb)^2+V(nb)^2-2*V(mb)*V(nb)*cos(delta(mb)-delta(nb)))','mb','nb');
% old code running
objf=inline('4*x1^2-2.1*x1^4+(x1^6)/3+x1*x2-4*x2^2+4*x2^4','x1','x2');**
*Error using inlineeval (line 15)
Error in inline expression ==> sum(V(mb).^2+V(nb).^2-2.*V(mb).*V(nb).cos(delta(mb)-delta(nb)))
Undefined function 'V' for input arguments of type 'double'.
Error in inline/subsref (line 24)
INLINE_OUT_ = inlineeval(INLINE_INPUTS_, INLINE_OBJ_.inputExpr, INLINE_OBJ_.expr);
Error in deeee (line 48)
fx=objf(x(:,1),x(:,2));
where variable aer defined as below..
busdata = bus; % ARRAY OF INPUTs
j=sqrt(-1);
P=[];Q=[];
nb=busdata(:,1);
kb=busdata(:,2);Vm=busdata(:,3);deltad=busdata(:, 4);Pd=0.8*busdata(:,5)/basemva;Qd=.8*busdata(:,6)/basemva;
Pg=busdata(:,7)/basemva;Qg=busdata(:,8)/basemva;Bsh=busdata(:,11);Qmin=busdata(:,9)/basemva;Qmax=busdata(:,10)/basemva;
G=real(Ybus);B=imag(Ybus);slb=find(kb==1);pv=find(kb==2);pq=find(kb==0);pvq=find(kb~=1);npv=length(pv);
npq=length(pq);npvq=length(pvq);nbus=max(nb);
delta(nb) = pi/180*deltad(nb);
V(nb) = Vm(nb).*(cos(delta(nb))+j*sin(delta(nb)))';
P(nb)=(Pg(nb)-Pd(nb));
flag=0;
What you're locking for is anonymous functions
objf = #(mb,nb)sum(V(mb)^2+V(nb)^2-2*V(mb)*V(nb)*cos(delta(mb)-delta(nb)))
objf =
#(mb,nb)sum(V(mb)^2+V(nb)^2-2*V(mb)*V(nb)*cos(delta(mb)-delta(nb)))
objf(1,2)
There you go (as far as all other variables and functions of this anonymous function are defined).

Ok, so I am trying to convert a list of CIDR formatted ip data into netranges
192.168.1.0/24 I need that, converted to 192.168.1.0-255
In fact, a whole list of addresses. Like this.
101.192.0.0/14
101.202.0.0/16
101.203.128.0/19
101.248.0.0/15
101.252.0.0/15
103.16.76.0/24
103.194.8.0/22
103.197.8.0/22
103.205.84.0/22
103.207.160.0/22
103.210.12.0/22
103.215.80.0/22
103.229.36.0/22
103.229.40.0/22
103.230.144.0/22
103.232.136.0/22
103.232.172.0/22
103.236.32.0/22
Is there any tools readily available that do this? I did some searching before posting this, but nobody else seems to be going for the specific output that I am trying to get here.
Just tried without external commands or libraries.
perl -pe '
m#^(\d+)\.(\d+)\.(\d+)\.(\d+)/(\d+)#;
$_ = "$1.$2.$3.$4-" . join(".", map(hex, sprintf("%X", ($1 << 24) + ($2 << 16) + ($3 << 8) + $4 | (1 << (32 - $5)) - 1) =~ /.{2}/g)) . "\n";
' iplist.txt
I provide the sample script using ipaddress.(Thank you for the instructions, #Jonathon Reinhart )
The prerequisite task is just installing ipaddress module.
# pip install ipaddress
script code: the cidr.list file is including above cidr list.
#!/usr/bin/env python
import ipaddress
file_path='/tmp/cidr.list'
with open(file_path,'r') as cidr_list:
for cidr in cidr_list:
tmp = ipaddress.ip_network(unicode(cidr[:-1]))
print "%s-%s" % (tmp[0],tmp[-1])
output:
101.192.0.0-101.195.255.255
101.202.0.0-101.202.255.255

I hope this will help you.
Update (thanks #TheAdminsHereAreFags for pointing out sipcalc)
If you have the sipcalc package installed
sipcalc - < iplist.txt | awk '/Network range/{print $4 $5 $6}'

Hi I want to create A YML file and load them as instance variables instead. How can I do that.
yml_File.yml File ::
default:
browserversion: 43
dev:
browser_02: iexplore
qa_01:
browser_default: chrome
qa_02:
browser_default: safari
Check the below Code::
p yml_File = YAML.load_file(File.dirname(__FILE__).gsub('/', '\\') + '\\Profiles.yml')
yml_File.each_key {|key_Value|
va = yml_File[key_Value].to_s
var_name = "##{key_Value}" # the '#' is required
self.instance_variable_set(var_name, va)
p "Name of Instance variable '#{key_Value}' is :: " + var_name.to_s + ' - And Key value is : ' + eval("##{key_Value}")
}
p #dev
p #qa_01
p #qa_02

I have quite the annoying bug right now, whenever I run this code
function player.detect()
for j = #bullet, 1, -1 do
if CheckCollision(bullet[j].x, bullet[j].y, bullet.w, bullet.h, enemy.x, enemy.y, enemy.w, enemy.h) then
table.remove(bullet, j)
end
end
end
for j = #enemy, 1, -1 do
if CheckCollision(bullet.x, bullet.y, bullet.w, bullet.h, enemy[j].x, enemy[j].y, enemy.w, enemy.h) then
table.remove(enemy, j)
end
end
end
end
It says: Error: Syntax error: player.lua:118: '' expected near 'end'
Yes, this is player.lua, and yes the code displayed is line 104-119. Thanks for reading! Anything helps!
You have too many ends!
function player.detect()
for j = #bullet, 1, -1 do
if CheckCollision(bullet[j].x, bullet[j].y, bullet.w, bullet.h, enemy.x, enemy.y, enemy.w, enemy.h) then
table.remove(bullet, j)
end
end
for j = #enemy, 1, -1 do
if CheckCollision(bullet.x, bullet.y, bullet.w, bullet.h, enemy[j].x, enemy[j].y, enemy.w, enemy.h) then
table.remove(enemy, j)
end

I need to convert this:

{"day"=>"2014-02-03", "users"=>3234},

[{:x=>1, y:=>1234},
{:x=>2, y:=>2234},
{:x=>3, y:=>3234},
{:x=>4, y:=>4234}]
a = [{"day"=>"2014-02-01", "users"=>1234}, {"day"=>"2014-02-02", "users"=>2234}, {"day"=>"2014-02-03", "users"=>3234}, {"day"=>"2014-02-04", "users"=>4234}]
a.map.with_index(1) { |h,i| { :x => i, :y => h['users'] } }

i want to load my image call caltrain, there is 30 img.
i used code
for i = 0:30
imgINumber = i;
imgPNumber = i+2;
if imgINumber < 10
imgIFile = sprintf('C:\sequence01_caltrain_gray\caltrain/gray/%s00%d.ras',imageName, imageName, imgINumber);
elseif imgINumber < 100
imgIFile = sprintf('C:\sequence01_caltrain_gray\caltrain/gray/%s0%d.ras',imageName, imageName, imgINumber);
end
if imgPNumber < 10
imgPFile = sprintf('C:\sequence01_caltrain_gray\caltrain\gray/%s00%d.ras',imageName, imageName, imgPNumber);
elseif imgPNumber < 100
imgPFile = sprintf('C:\sequence01_caltrain_gray\caltrain\gray/%s0%d.ras',imageName, imageName, imgPNumber);
end
imgI = double(imread(imgIFile));
imgP = double(imread(imgPFile));
imgI = imgI(:,1:352);
imgP = imgP(:,1:352);
but error:
Error using ==> imread

i need solution for this

Either double your backslashes or replace all the backslashes with slashes in your sprintf calls.
