Problem 581. Function composition
Write a function that accepts two function handles f and g and returns the composition h. That is,
h = (f o g)(x) = f(g(x))
Example:
>> f = @(x)x^2; >> g = @(x)x+1; >> h = composeFcn(f,g); >> h(3) ans = 16
because (3+1)^2 = 16.

@善翔 韩, syms is a part of symbolic toolbox and toolboxes are not available on cody.
