pivot de gauss algorithme python

Élimination de Gauss-Jordan en Python. Ask Question Asked 11 years, 11 months ago. 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. However, python counts from 0, meaning that the last element is -1 smaller than expected. Follow @python_fiddle url: Go Python Snippet Stackoverflow Question.
