scipy.linalg.blas.srotmg#
- scipy.linalg.blas.srotmg(d1, d2, x1, y1) = <fblas function srotmg>#
Construct a modified Givens rotation (BLAS
srotmg).- Parameters:
- d1float
Scaling factor for the first coordinate.
- d2float
Scaling factor for the second coordinate.
- x1float
First coordinate of the vector to rotate.
- y1float
Second coordinate of the vector to rotate.
- Returns:
- paramndarray
Length-5 array describing the rotation:
param[0]is a flag selecting the matrix form andparam[1:5]are its entries.
