- scipy.linalg.blas.crotg(a, b) = <fblas function crotg>#
Construct a Givens plane rotation
(c, s)that eliminates b (BLAScrotg).- Parameters:
- acomplex
First component of the vector to rotate.
- bcomplex
Second component of the vector to rotate.
- Returns:
- ccomplex
Cosine of the rotation. Its imaginary part is zero.
- scomplex
Sine of the rotation.
