A question about sum_square_abs

Suppose a complex N dimensional vector x \in {{\mathbb C}^{N \times 1}}, is the code “square_pos(norm(x))” equal to the “sum_square_abs(x)”?

That is correct. …

Thanks. I have one last question. I have a matrix variable W \in {{\mathbb C}^{N \times L}}, and the objective function is \mathop {\min }\limits_W {\left\| W \right\|_F}, where {\left\| \cdot \right\|_F} is the Frobenius norm. Is that can be written as minimize(norm(W,‘fro’)) in cvx solver?

That is correct. …… .
