In the paper the authors present the WZ factorization in MATLAB. MATLAB is an environment for matrix computations, therefore in the paper there are presented both the sequential WZ factorization and a block-wise version of the WZ factorization (called here VWZ). Both the algorithms were implemented and their performance was investigated. For random dense square matrices with the dominant diagonal we report the execution time of the WZ factorization in MATLAB and we investigate the accuracy of such solutions. Additionally, the results (time and accuracy) for our WZ implementations were compared to the similar ones based on the LU factorization.(original abstract)
