naginterfaces.library.blas.dlhous¶
- naginterfaces.library.blas.dlhous(z, z1, alpha, x)[source]¶
dlhous
applies a LINPACK (as opposed to NAG) style real elementary reflection to a real vector.For full information please refer to the NAG Library document for f06fu
https://support.nag.com/numeric/nl/nagdoc_30.2/flhtml/f06/f06fuf.html
- Parameters
- Returns
- alphafloat
The transformed scalar .
- xfloat, ndarray, shape
The transformed vector .
- Notes
No equivalent traditional C interface for this routine exists in the NAG Library.
dlhous
applies a real elementary reflection (Householder matrix) , as generated bydlhousg()
, to a given real vector:where is an -element real vector and a real scalar.
