### Test Suite

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

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 3) b = find(a == a^2); Error in Test1 (line 2) assert(isequal(isItSquared(a),true))

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

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 3) b = find(a == a^2); Error in Test2 (line 2) assert(isequal(isItSquared(a),false))

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

4   Fail
