Description
Given two vectors
x
 and
y
, the
?swap
 routines return vectors
y
 and
x
 swapped, each replacing the other.
Input Parameters
n
Specifies the number of elements in vectors
x
 and
y
.
x
Array, size at least
(1 + (
n
-1)*abs(
incx
))
.
incx
Specifies the increment for the elements of
x
.
y
Array, size at least
(1 + (
n
-1)*abs(
incy
))
.
incy
Specifies the increment for the elements of
y
.
Output Parameters
x
Contains the resultant vector
x
, that is, the input vector
y
.
y
Contains the resultant vector
y
, that is, the input vector
x
.
