`scipy.linalg._flapack:zgetri`

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

Summary

Invert a matrix from its getrf factorization (LAPACK zgetri).

Parameters

lu : ndarray: Combined L and U factors, as returned by getrf.
piv : ndarray: Pivot indices from getrf, 0-based.
lwork : int, optional: Size of the workspace; must be at least n. Default is 3 * n. Use getri_lwork for the optimal value.
overwrite_lu : int, optional: If nonzero, lu may be overwritten in place. Default is 0.

Returns

inv_a : ndarray: Inverse of the matrix lu was factorized from.
info : int: 0 on success; if negative, the -info-th argument had an illegal value; if positive, u[info-1, info-1] is exactly zero and the matrix is singular.
