### 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: @(fh)fh(fh)

Array indices must be positive integers or logical values. Error in iterate_fcn>@(fh)fh(fh) (line 3) fh = @(fh)fh(fh); Error in Test1 (line 3) assert(isequal(fh2(pi),pi));

2   Fail
addOne = @(x)x+1; addTen = iterate_fcn(addOne, 10); assert(isequal(addTen(3),13));

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

Index exceeds the number of array elements (1). Error in iterate_fcn>@(fh)fh(fh) (line 3) fh = @(fh)fh(fh); Error in Test2 (line 3) assert(isequal(addTen(3),13));

3   Fail
addOne = @(x)x+1; addOne2 = iterate_fcn(addOne, 1); assert(isequal(addOne2(3),4));

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

Index exceeds the number of array elements (1). Error in iterate_fcn>@(fh)fh(fh) (line 3) fh = @(fh)fh(fh); Error in Test3 (line 3) assert(isequal(addOne2(3),4));

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

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

Index exceeds the number of array elements (1). Error in iterate_fcn>@(fh)fh(fh) (line 3) fh = @(fh)fh(fh); Error in Test4 (line 3) assert(isequal(fh2(3),6561));

5   Fail
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: @(fh)fh(fh)

Assertion failed.
