Parameters
pSrc
Pointer to the source vector.
pDst
Pointer to the destination vector.
pSrcDst
Pointer to the source and destination vector for the in-place operation.
len
Number of elements in the vector.
Description
This function stores in
pDst
the element-wise conjugation of the complex vector
pSrc
. The element-wise conjugation of the vector is defined as follows:
pDst
[n].
re
=
pSrc
[n].
re
pDst
[n].
im
= -
pSrc
[n].
im
The in-place flavors of
ippsConj
store in
pSrcDst
the element-wise conjugation of the complex vector
pSrcDst
.
The element-wise conjugation of the vector is defined as follows:
pSrcDst
[n].
re
=
pSrcDst
[n].
re
pSrcDst
[n].
im
= -
pSrcDst
[n].

Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when the
pSrc
,
pDst
,
or pSrcDst
pointer is
NULL
.
ippStsSizeErr
Indicates an error when
len
is less than or equal to 0.

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.
