Slinalg.SEF
Computes the row echelon form of a sparse matrix over F2.
Syntax
Slinalg.SEF(NRow:INT, NCol:INT, M:LIST): LIST Slinalg.SEF_v2(NRow:INT, NCol:INT, M:LIST): 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 M: List of lists containing positions of non zero elements.
@return A list of lists containing the row echelon form of the matrix M.
Example
Use ZZ/(2)[x]; NRow:=10; NCol:=13; 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]]; 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]] -------------------------------
