Test Status Code Input and Output
1   Pass
x = [1 2.2 3.3 4]; y_correct = [true false false true]; assert(isequal(checkIfinteger(x),y_correct))

ans = 1×4 logical array 1 0 0 1

2   Pass
x = [-1 2 3.3 4 -7.54]; y_correct = [true true false true false]; assert(isequal(checkIfinteger(x),y_correct))

ans = 1×5 logical array 1 1 0 1 0

3   Pass
x = [pi 2.2 single(3.78) -4.34 eps inf] ; y_correct = [false false false false false false]; assert(isequal(checkIfinteger(x),y_correct))

ans = 1×6 logical array 0 0 0 0 0 0

4   Pass
x = [1.0 0 nan -6.0]; % infact nan is 'not a number' y_correct = [true true false true]; assert(isequal(checkIfinteger(x),y_correct))

ans = 1×4 logical array 1 1 0 1

5   Fail
x = [true false logical(0) logical(1)] y_correct = [false false false false]; assert(isequal(checkIfinteger(x),y_correct))

x = 1×4 logical array 1 0 0 1 ans = 1×4 logical array 1 1 1 1

Assertion failed.

6   Fail
x = ['1' '2' 'a' 'b' '!'] y_correct = [false false false false false]; assert(isequal(checkIfinteger(x),y_correct))

x = '12ab!' ans = 1×5 logical array 1 1 1 1 1

Assertion failed.
