Passing functions as arguments in Matlab

Question

I\'m trying to write a function that is gets two arrays and the name of another function as arguments.

e.g.

main.m:

    x=[0 0.2 0.4 0.6 0.8 1.0];
         


        

Answer 1

You could try in func2.m:

function t = func2(x, y, funcName)  % no quotes around funcName
    func = str2func(funcName)
    t = func(x, y)
end

Answer 2

You could also use function handles rather than strings, like so:

main.m:

...
func2(x, y, @func2eq); % The "@" operator creates a "function handle"

This simplifies func2.m:

function t = func2(x, y, fcnHandle)
    t = fcnHandle(x, y);
end

For more info, see the documentation on function handles
