Slinalg.SEF
Calculates the Echelon form of a sparse matrix over F2.
Syntax
Slinalg.SEF(NRow : INT ,NCol : INT, Mat : LIST)
Description
Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.
@param NRow: Number of rows of the matrix.
@param NCol: Number of Columns of the matrix.
@param Mat: List of lists containing positions of non zero elements.
@return A list of lists containing the Echelon form of the matrix.
Example
Use ZZ/(2)[x]; M := [[1, 2, 6, 7], [1, 2, 4, 5, 6], [2, 3], [2, 3, 10, 11], [2, 4, 6, 7, 9, 10], [2, 10, 11, 13], [5, 6, 8], [ 6, 8, 9, 10,12],[6, 10, 12], [ 10, 13]]; NRow:=10; NCol:=13; Slinalg.SEF(NRow, NCol, M); [[1,2,6,7],[2,3],[3,4,6,7,9,10],[4,5,7],[5,6,8],[6,8,9,10,12],[8,9,11,13],[10,11],[11,13]] -------------------------------
