scipy.linalg.lapack.zlartg#
- scipy.linalg.lapack.zlartg(f, g) = <flapack function zlartg>#
Generate a Givens rotation (LAPACK
zlartg).Produces
csandsnwith[[cs, sn], [-conj(sn), cs]] @ [f, g] == [r, 0].- Parameters:
- fcomplex
First component.
- gcomplex
Second component, the one rotated to zero.
- Returns:
- csfloat
The cosine. Real for every flavor.
- sncomplex
The sine.
- rcomplex
The resulting first component.
