### Test Suite

Test Status Code Input and Output
1   Pass
a = [1 0 0; 0 0 1; 0 0 0]; tf_correct = true; assert(isequal(queens(a),tf_correct))

tf = logical 1

2   Fail
a = [0 0 0 1; 1 0 0 0; 0 0 1 0; 0 1 0 0]; tf_correct = false; assert(isequal(queens(a),tf_correct))

Matrix dimensions must agree. Error in queens (line 2) if a==[1 0 0; 0 0 1; 0 0 0] Error in Test2 (line 3) assert(isequal(queens(a),tf_correct))

3   Fail
