Aug 16, 2019 at 21:37 comment added Jacob Di I see now. You are right.
Aug 16, 2019 at 20:41 comment added Federico Poloni No, you can't. What that formula computes is the projection of $x$ over the range of $N$. For instance, if $N=[1, 0]^T$, then $x=[1,1]^T$ satisfies the inequality in your comment, but not the one in your question.
Aug 16, 2019 at 20:31 comment added Jacob Di In my case, $N$ is full column rank. Can I do $N^\top x = N^\top N \lambda$, solve for $\lambda = (N^\top N)^{-1}N^\top x \geq 0$ ?
