C++: std::bind -> std::function - c++11

Question

I have several functions which receive the following type:
function<double(int,int,array2D<vector<double *>>*)>
Where array2D is a custom type. Further, I have a function which takes the following as arguments:
double ising_step_distribution(double temp,int i,int j,array2D<vector<double *>>* model)
Right now, in order to bind the first value, temp, and return a functor which has the correct signature, I am writing:
double temp = some_value;
function<double(int,int,array2D<vector<double *>>*)> step_func =
[temp](int i, int j, array2D<vector<double *>>* model){
return ising_step_distribution(temp,i,j,model);
}
}
And this works. However, the following breaks:
auto step_func =
[temp](int i, int j, array2D<vector<double *>>* model){
return ising_step_distribution(temp,i,j,model);
}
}
With the following error:
candidate template ignored:
could not match
'function<double (int, int, array2D<vector<type-parameter-0-0 *, allocator<type-parameter-0-0 *> > > *)>'
against
'(lambda at /Users/cdonlan/home/mcmc/main.cpp:200:25)'
void mix_2D_model(function<double(int,int,array2D<vector<T*>>*)> step_distribution_func,...
And so, the code clump is ugly, obfuscative and repetitive (because I am making many of these).
I have been reading the documentation, and I understand that I should be able to write:
function<double(int,int,array2D<vector<double *>>*)> step_func =
bind(ising_step_distribution,temp,_1,_2,_3);
However, the only examples I have seen are for functions of type function<void()>. This one fails with an error:
// cannot cast a bind of type
// double(&)(double,int,int,array2D<vector<double *>>*)
// as function<double(int,int,...)
How do I get a visually clean bind and cast?

How do I get a visually clean bind and cast?
One way is:
using F = function<double(int,int,array2D<vector<double *>>*)>;
auto step_func =
[temp](int i, int j, array2D<vector<double *>>* model){
return ising_step_distribution(temp,i,j,model);
}
}
And then:
auto step_func_2 = F(step_func);
mix_2D_model(step_func_2, ...);
Or:
mix_2D_model(F(step_func), ...);
