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
.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
