- scipy.linalg.blas.drotm(x, y, param, n=None, offx=0, incx=1, offy=0, incy=1, overwrite_x=0, overwrite_y=0) = <fblas function drotm>#
Apply a modified Givens rotation to x and y (BLAS
drotm).- Parameters:
- xndarray
Input/output vector.
- yndarray
Input/output vector.
- paramndarray
Length-5 array describing the rotation, as returned by
rotmg.- nint, optional
Number of elements to process. Default is the whole vector.
- offxint, optional
Index of the first element of x to use. Default is 0.
- incxint, optional
Stride between successive elements of x. Default is 1.
- offyint, optional
Index of the first element of y to use. Default is 0.
- incyint, optional
Stride between successive elements of y. Default is 1.
- overwrite_xint, optional
If nonzero, x may be overwritten in place. Default is 0.
- overwrite_yint, optional
If nonzero, y may be overwritten in place. Default is 0.
- Returns:
- xndarray
The transformed vector x.
- yndarray
The transformed vector y.
