Parameters
- pDst
- Pointer to the destination vector.
- len
- Number of elements in the vector.
- magn
- Magnitude of the signal to be generated.
Description
This function creates a Jaehne vector and stores the result in
pDst
. The magnitude
magn
must be
positive. The function generates the sinusoid with a variable frequency. The
computation is performed as follows:pDst
[n
] = magn
* sin ((0.5πn
2
)/len
)0
≤
n < len
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepSrcDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to 0.
- ippStsJaehneErr
- Indicates an error whenmagnis negative.
Example
The code example below shows how to use the function
ippsVectorJaehne
.IppStatus Jaehne (void) { Ipp16s buf[100] ; return ippsVectorJaehne_16s ( buf, 100, 255 ); }
