Test Status Code Input and Output
1   Fail
a = [2 3 4]; assert(isequal(isItSquared(a),true))

c = 1 3

Error using ^ (line 51) Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a scalar. To perform elementwise matrix powers, use '.^'. Error in isItSquared (line 4) if find(a==a^2) Error in Test1 (line 2) assert(isequal(isItSquared(a),true))

2   Fail
a = [20:30]; assert(isequal(isItSquared(a),false))

c = 1 11

Error using ^ (line 51) Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a scalar. To perform elementwise matrix powers, use '.^'. Error in isItSquared (line 4) if find(a==a^2) Error in Test2 (line 2) assert(isequal(isItSquared(a),false))

3   Fail
a = [1]; assert(isequal(isItSquared(a),true))

c = 1 1

Assertion failed.
