Linear regression to a matrix

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!

P = polyfit(X,Y,1)

For this refer: https://in.mathworks.com/help/matlab/data_analysis/linear-regression.html

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