scipy.linalg.blas.drotg

scipy.linalg.blas.drotg(a, b) = <fblas function drotg>

Construct a Givens plane rotation (c, s) that eliminates b (BLAS drotg).

Parameters:

afloat

First component of the vector to rotate.

bfloat

Second component of the vector to rotate.

Returns:

cfloat

Cosine of the rotation.

sfloat

Sine of the rotation.
