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
, or
pSrcDst
 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)'
