| Abstract: | 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. |
