QR factorization of row(column) antisymmetric matrices

YUAN Hui-ping (College of Mathematics and Statistics,Chongqing Technology and Business University,Chongqing 400067,China)  
The concept of row(column) transposed matrix and row(column) skew symmefric matrix were defined.Their basic property were studied and some new results were gained.The formula for the QR factorization of row(column) skew symmefric matrix were obtained.Those formula could dramatically reduce the amount of calculation for QR factorization of row(column) skew symmefric matrix,save dramatically the CPU time and memory without loss of any numerical precision.
