scipy.linalg.lapack.sgesc2#
- scipy.linalg.lapack.sgesc2(lu, rhs, ipiv, jpiv, overwrite_rhs=0) = <flapack function sgesc2>#
Solve a system factorized by
getc2, scaling to avoid overflow (LAPACKsgesc2).- Parameters:
- lundarray
Combined
LandUfactors, as returned bygetrf.- rhsndarray
Right-hand side vector of length
n.- ipivndarray
Row pivot indices from
getc2, 0-based.- jpivndarray
Column pivot indices from
getc2, 0-based.- overwrite_rhsint, optional
If nonzero, rhs may be overwritten in place. Default is 0.
- Returns:
- xndarray
Solution, scaled by scale to avoid overflow.
- scalefloat
Scale factor applied to the right-hand side,
0 <= scale <= 1.
