I want to solve xA=b with constraint 0<=x for x.
I found functions like lsqnonneg and lsqlin which solves for Ax=b. However, couldn't find a good way to solve for xA=b.
How can I solve xA=b with non-negative x constraint?

As David commented, it is straightforward to show that
so you can use standard methods to solve the problem with A' and b' and then transpose the answer.
