How do I factorize a matrix(m x n) into two factors (m x r, r x n) in Matlab? -
i want start mxn matrix , factorise 2 matrices mxr , rxn. r can greater dimensions of matrix a.
nnmf allows r< min(size(a))
is there way can factorise matrix 2 matrices?
there factorization functions available in matlab, see here: http://www.matrixlab-examples.com/matrix-decomposition.html
e.g. lu / qr - factorization, cholesky etc...
