WinBartlett
Multiplies a vector by a Bartlett windowing function.
Syntax

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 the pSrc, pDst, orpSrcDst pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is 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)'
