scipy.linalg.blas.zscal#
- scipy.linalg.blas.zscal(a, x, n=None, offx=0, incx=1) = <fblas function zscal>#
Scale x in place by a:
x = a*x(BLASzscal).- Parameters:
- acomplex
Scalar multiplier.
- xndarray
Input/output vector; overwritten with
a*x.- 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.
- Returns:
- xndarray
The scaled vector
a*x.
