`scipy.linalg._fblas:sswap`

Signature

def sswap(x, y, n = None, offx = 0, incx = 1, offy = 0, incy = 1)

Swap the contents of x and y in place (BLAS sswap).

x : ndarray: Input/output vector; on exit it holds the original y.
y : ndarray: Input/output vector; on exit it holds the original x.
n : int, optional: Number of elements to process. Default is the whole vector.
offx : int, optional: Index of the first element of x to use. Default is 0.
incx : int, optional: Stride between successive elements of x. Default is 1.
offy : int, optional: Index of the first element of y to use. Default is 0.
incy : int, optional: Stride between successive elements of y. Default is 1.
