minimize (A,B) of

, where F denotes Frobenius norm

constraints

= n

where diamension of A = m x n, and B = p x m

X is the matrix you want to determine and A and B are given ? Or the other way round ?

And you want to minimize ||X-AB|| and at the same time put the constraint ||X-AB||=n ? Strange ...

Actually I want to find matrix B , where X and A is given. thats all.

Should we proceed like X - AB ~= 0.

=> B ~= inv(A)*X. or in the other ways.
