Test	Status	Code Input and Output
1	Fail	%% a = [2 3 4]; assert(isequal(isItSquared(a),true)) Error: Inputs must be a scalar and a square matrix. To compute elementwise POWER, use POWER (.^) instead.
2	Fail	%% a = [20:30]; assert(isequal(isItSquared(a),false)) Error: Inputs must be a scalar and a square matrix. To compute elementwise POWER, use POWER (.^) instead.
3	Pass	%% a = [1]; assert(isequal(isItSquared(a),true))
4	Fail	%% a = [6 10 12 14 36 101]; assert(isequal(isItSquared(a),true)) Error: Inputs must be a scalar and a square matrix. To compute elementwise POWER, use POWER (.^) instead.
