Hello,

I would like to know how can I solve the following Linear Least Squares problem:

arg min(x) (Ax - b)'(Ax - b)

s.t.

Ax >= c

Ax <= d

Is there a way to it in MATLAB?

The Constrained Linear Least Squares in MATLAB only allows one inequality.

Thank You.

It simply is not true that lsqlin only allows one constraint. READ THE HELP.

在 MATLAB Online 中打开

[-A ; A]*x <= [-c ; d]

So choose the matrix in lsqlin as [-A ; A] and the right-hand side vector as [-c ; d].

Best wishes

Torsten.

This is exactly what I did. But I will mark your question.

Thank You.
