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 multiplies the vector
pSrc
by the Bartlett (triangle) window, and stores the result in pDst
. The in-place flavors of
ippsWinBartlett
multiply the pSrcDst
by the Bartlett (triangle) window and store the result in pSrcDst
.The complex types multiply both the real and imaginary parts of the vector by the same window.
The Bartlett window is defined as follows:
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepSrc,pDst, orpSrcDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than 3.
Example
The example below shows how to use the function
ippsWinBartlett_32f_I
.void bartlett(void) { Ipp32f x[8]; ippsSet_32f(1, x, 8); ippsWinBartlett_32f_I(x, 8); printf_32f(“bartlett (half) =”, x, 4, ippStsNoErr); }
Output:
bartlett (half) = 0.000000 0.285714 0.571429 0.857143 Matlab* Analog: >> b = bartlett(8); b(1:4)'
