3. Last element are x[2] and M[2][3]. Message par phyX » 17 mars 2014 18:43 Bonsoir, En cours nous avons abordé la méthode du pivot de Gauss … pivot_value = matrix[0, 0] if pivot_value: matrix[1:] -= (matrix[0] / pivot_value) * matrix[1:, 0] In swap_rows, it is misleading to name the arguments a and b, since elsewhere in the code you are using b for a column vector, but here b needs to be an index.

De nitions The Algorithm Solutions of Linear Systems Answering Existence and Uniqueness questions Pivots Leading Entries and Pivot Positions De nition A pivot position of a matrix A is a location that corresponds to a leading entry of the reduced row echelon form of A, i.e., a ij is in a pivot position if an only if RREF(A) ij = 1. The following ultra-compact Python function performs in-place Gaussian elimination for given matrix, putting it into the Reduced Row Echelon Form.
