`scipy.linalg._flapack:dpotrs`

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

Signature

def dpotrs(c, b, lower = 0, overwrite_b = 0)

Summary

Solve a positive definite system using the factorization from potrf (LAPACK dpotrs).

Parameters

c : ndarray: Cholesky factor, as returned by potrf.
b : ndarray: Right-hand side(s) of shape (n, nrhs).
lower : int, optional: If nonzero, c is the lower triangular factor; otherwise the upper. Must match what was passed to potrf. 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.
