TY - JOUR JF - IJMSI JO - IJMSI VL - 17 IS - 1 PY - 2022 Y1 - 2022/4/01 TI - On the WZ Factorization of the Real and Integer Matrices TT - N2 - The textit{QIF} (Quadrant Interlocking Factorization) method of Evans and Hatzopoulos solves linear equation systems using textit{WZ} factorization. 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}.
