### Test Suite

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

fh2 = function_handle with value: @(x)x fh2 = function_handle with value: @(x)fh(fh2(x))

2   Fail

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

Assertion failed.

3   Pass

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

4   Fail
squarer = @(a) a^2; fh2 = iterate_fcn(squarer, 3); assert(isequal(fh2(3),6561));

fh2 = function_handle with value: @(a)a^2 fh2 = function_handle with value: @(x)fh(fh2(x))

Assertion failed.

5   Pass
fh = @(y)sqrt(y+1); fh2 = iterate_fcn(fh,30); assert(abs(fh2(1) - (1+sqrt(5))/2) < 100*eps);

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