Hi,

Suppose there is an observed matrix

, how can I find a linear regression (

) via

, where

is a given matrix, and

=ones(m,n)?

As I know, Matlab provides some solutions for the case of the obseved vector

, such as regress, but not for the observed matrix.

Thanks!

Your question is very clear. How did you solve this problem? can you share？thanks a lot

P = polyfit(X,Y,1)

The polyfit gives you approximate, using the above is more apt.
