Things to bear in mind if you save a function handle in a mat file:
- When you load the mat file, the function that handle points to must be on the path.
- If a different function with the same name is on the path when you load the mat file, that function will be called instead.
Instead of a function handle, you could store an anonymous function. Variables in scope are permanently bound to an anonymous function when it is created. e.g:
a = 5;
b = 3;
fh = @(x) a+x-b;
fh(1) %return 3
%at this point a and b are bound to the anonymous function.
%changing their value does not affect the anonymous function
a = 0;
b = Inf;
fh(1) %still return 3
%even deleting them does not affect the anonymous function
clear a b
fh(1) %still return 3
Whether or not that can work for you, I'm not sure. It really depends on what the inputs to your function are.
