Description
The routine conjugates a complex vector
x
 of length
n
 and increment
incx
 (see "Vector Arguments in BLAS" in Appendix B).
Input Parameters
A
<datatype>
 placeholder, if present, is used for the C interface data types in the C interface section above. See C Interface Conventions for the C interface principal conventions and type definitions.
n
The length of the vector
x
 (
n
≥
 0
).
x
Array, dimension
(1+(
n
-1)* |
incx
|)
.
Contains the vector of length
n
 to be conjugated.
incx
The spacing between successive elements of
x
.
Output Parameters
x
On exit, overwritten with
conjg
(
x
).

Product and Performance Information

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. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
