`scipy.linalg._flapack:cgetrf`

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

Signature

def cgetrf(a, overwrite_a = 0)

Summary

Compute the LU factorization a = p @ l @ u with partial pivoting (LAPACK cgetrf).

Parameters

a : ndarray: Matrix of shape (m, n).
overwrite_a : int, optional: If nonzero, a may be overwritten in place. Default is 0.

Returns

lu : ndarray: Combined L and U factors; the unit diagonal of L is not stored.
piv : ndarray: Pivot indices, 0-based: row i was interchanged with row piv[i].
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 factor is singular.
