`scipy.linalg._flapack:dgetrs`

source: build-install/usr/lib/python3.14/site-packages/scipy/linalg/_flapack.cpython-314-x86_64-linux-gnu.so

Signature

def dgetrs(lu, piv, b, trans = 0, overwrite_b = 0)

Summary

Solve a system already factorized by getrf (LAPACK dgetrs).

Parameters

lu : ndarray: Combined L and U factors, as returned by getrf.
piv : ndarray: Pivot indices from getrf, 0-based.
b : ndarray: Right-hand side(s) of shape (n, nrhs).
trans : int, optional: System to solve: 0 for a @ x = b, 1 for a.T @ x = b, 2 for a.conj().T @ x = b. Default is 0.
overwrite_b : int, optional: If nonzero, b may be overwritten in place. Default is 0.

Returns

x : ndarray: Solution of the system.
info : int: 0 on success; if negative, the -info-th argument had an illegal value.
