That was amazingly hard! Never used function handles. And I think i never will...

Interesting to see you used the same variable name for both input and output of your nested function.

Test	Status	Code Input and Output
1	Pass	%% noOp = @(x)x; fh2 = iterate_fcn(noOp, 50); assert(isequal(fh2(pi),pi));
2	Pass	%% addOne = @(x)x+1; addTen = iterate_fcn(addOne, 10); assert(isequal(addTen(3),13));
3	Pass	%% addOne = @(x)x+1; addOne2 = iterate_fcn(addOne, 1); assert(isequal(addOne2(3),4));
4	Pass	%% squarer = @(a) a^2; fh2 = iterate_fcn(squarer, 3); assert(isequal(fh2(3),6561));
5	Pass	%% fh = @(y)sqrt(y+1); fh2 = iterate_fcn(fh,30); assert(abs(fh2(1) - (1+sqrt(5))/2) < 100*eps);
