Hi
If I understand your problem correctly you can do something like this:

function [ ret ] = some_name (a, b, x)
   ret = a(x) + b(x);
endfunction

And then call this function with arguments like this:

some_name(  at sin, @cos, 3)

which will give you the value of sin(3) + cos(3)

hope that helps,
Søren
