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

Signature

def dpttrs(d, e, b, overwrite_b = 0)

Summary

Solve a positive definite tridiagonal system using the factorization from pttrf (LAPACK dpttrs).

Parameters

d : ndarray: Diagonal of D from pttrf. Real for every flavor.
e : ndarray: Off-diagonal of L from pttrf.
b : ndarray: Right-hand side(s) of shape (n, nrhs).
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.
