摘要
论述了Ｆ线与列上零位组之间的联系：在矩阵元素为有理数的假定下，简化了矩阵Ｆ算法的证明：改进了矩阵Ｆ算法．从而提高了其运算效率．
In this paper. we discuss the relation between the F-line and the zeroposition group on the column. under the condition that the elements of thematrix are rational numbers. simplify the proof of the F algorithm of matrix andimprove the F algorithm of matrix. Therefore. it speeds up the calculation.
