Linear regression to a matrix
显示 更早的评论
Hi,
Suppose there is an observed matrix 
, how can I find a linear regression (
) via 
, where 
is a given matrix, and 
=ones(m,n)?
, 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.
, such as regress, but not for the observed matrix.Thanks!

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