arXiv - CS - Symbolic Computation Pub Date : 2020-10-14 , DOI: arxiv-2010.06998
Dong Lu, Dingkang Wang, Fanghui Xiao

A new necessary and sufficient condition for the existence of minor left prime factorizations of multivariate polynomial matrices without full row rank is presented. The key idea is to establish a relationship between a matrix and its full row rank submatrix. Based on the new result, we propose an algorithm for factorizing matrices and have implemented it on the computer algebra system Maple. Two examples are given to illustrate the effectiveness of the algorithm, and experimental data shows that the algorithm is efficient.
