scipy.linalg.blas.zdscal#
- scipy.linalg.blas.zdscal(a, x, n=None, offx=0, incx=1, overwrite_x=0) = <fblas function zdscal>#
Scale complex x by the real scalar a:
x = a*x(BLASzdscal).- Parameters:
- afloat
Real scalar multiplier.
- xndarray
Complex input vector.
- 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.
- overwrite_xint, optional
If nonzero, x may be overwritten in place. Default is 0.
- Returns:
- xndarray
The scaled vector
a*x.
