source: /scipy/optimize/_remove_redundancy.py :235

Signature

def _remove_redundancy_pivot_sparse ( A , rhs )

Summary

Eliminates redundant equations from system of equations defined by Ax = b and identifies infeasibilities.

Parameters

A : 2-D sparse array: An matrix representing the left-hand side of a system of equations
rhs : 1-D array: An array representing the right-hand side of a system of equations

Returns

A : 2-D sparse array: A matrix representing the left-hand side of a system of equations
rhs : 1-D array: An array representing the right-hand side of a system of equations
: status: int: An integer indicating the status of the system 0: No infeasibility identified 2: Trivially infeasible
message : str: A string descriptor of the exit status of the optimization.
