摘要：

The concept of row (column) transposed matrix and row (column) antisymmetric matrix are given, their basic property are studied, and some new results are obtained. The formula for the LDU factorization and. Cholesky factorization of row (column) antisymmetric matrix are given. These formula can dramatically reduce the amount of calculation for LDU factorization and Cholesky factorization of row (column) antisymmetric matrix, save dramatically the CPU time and memory without loss of any numerical precision.
