matrix decomposition



Hello,

 

           Is there a way of obtaining the modified M=P.L.U1.R matrix
decomposition in maxima, with permutation matrix P, the square unit
lower triangular L factor, the square upper triangular factor U1, and
the unique reduced row-echelon form R of a Matrix M? I only found the
lu_factor decomposition. 

 

Thanks for your help.

 

Regards,
