https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Cross-Correlation-with-vsldCorrExec1D/m-p/822321#M4894 I'm trying to transliterate some Matlab code and am unsure how vlsdCorrExec1D corresponds to Matlab's xcorr function. xcorr has an output array that is of size 2*xshape-1<BR /><BR />Using that for zshape when calling vsldNewTask1D causes an error -2303 when calling vsldCorrExec1d.<BR /><BR />What am I missing?

If you set decimation parameter:<BR /> The root of aproblem is decimation parameter. <BR /><BR />2. If youdon't setdecimation parameter:<BR /> Of course we set defaultdecimation parameter but in this case the root of the problem is bad zshape. Typical zsape = xshape + yshape 1.</P><P><BR />Victor</P> Wed, 19 Jan 2011 06:20:23 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Cross-Correlation-with-vsldCorrExec1D/m-p/822322#M4895 Victor_Gladkikh 2011-01-19T06:20:23Z
