MATLAB: Function names as variables

Question

I have created functions (say func1 and func2) with this format (each of which was written in a separate file)

—————————————-

function [a,b]=func1

a=[1,1];

b=[0,0,0];

end

——————————————

function [a,b]=func2

a=[5,5];

b=[1,1,0];

end

————————————-

A statement like

[c,d]=func1;

works. However, it doesn't work when it is written in another function (call it mainfunc) which has func1 or func2 as arguments, i.e. briefly something like

mainfunc(x)

[c,d]=x;

where x is one of the functions func1 and func2.

Are there any suggestions to overcome this problem?

Answer 1

If you have

function [c, d] = mainfunc(x)

where x is being passed in as @func1 or @func2, then you would use

[c, d] = x();

With what you had, you were trying to return the function handle, rather than trying to return the result of invoking the function handle.
