### Test Suite

Test Status Code Input and Output
1   Fail
noOp = @(x)x; fh2 = iterate_fcn(noOp, 50); assert(isequal(fh2(pi),pi));

fh2 = function_handle with value: @(x)x

Assertion failed.

2   Fail

fh2 = function_handle with value: @(x)x+1

Undefined function 'plus' for input arguments of type 'function_handle'. Error in Test2>@(x)x+1 (line 1) addOne = @(x)x+1; Error in iterate_fcn>@(x)fh(fh2) (line 5) fh2 = @(x) fh(fh2); Error in Test2 (line 3) assert(isequal(addTen(3),13));

3   Pass

fh2 = function_handle with value: @(x)x+1

4   Fail
