scipy.linalg.lapack.dpotrs#
- scipy.linalg.lapack.dpotrs(c, b, lower=0, overwrite_b=0) = <flapack function dpotrs>#
Solve a positive definite system using the factorization from
potrf(LAPACKdpotrs).- Parameters:
- cndarray
Cholesky factor, as returned by
potrf.- bndarray
Right-hand side(s) of shape
(n, nrhs).- lowerint, optional
If nonzero, c is the lower triangular factor; otherwise the upper. Must match what was passed to
potrf. Default is 0.- overwrite_bint, optional
If nonzero, b may be overwritten in place. Default is 0.
- Returns:
- xndarray
Solution of the system.
- infoint
0 on success; if negative, the
-info-th argument had an illegal value.
