The WZ factorization can be faster than the textit{LU} factorization because, it performs the simultaneous evaluation of two columns or two rows. Here, we present a method for computing the real and integer textit{WZ} and textit{ZW} factorizations by using the null space generators of some special nested submatrices of a matrix textit{A}. %> http://ijmsi.ir/article-1-1358-en.pdf %P 71-83 %& 71 %! %9 Research paper %L A-10-3674-1 %+ Department of Mathematics, University of Qom, Qom, Iran %G eng %@ 1735-4463 %[ 2022
