Cross Correlation with vsldCorrExec1D

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

Using that for zshape when calling vsldNewTask1D causes an error -2303 when calling vsldCorrExec1d.

What am I missing?

Hi,

this error=-2303 isVSL_CC_ERROR_DECIMATION, that really mean bad decimation parameter.

1. If you set decimation parameter:
The root of aproblem is decimation parameter.

2. If youdon't setdecimation parameter:
Of course we set defaultdecimation parameter but in this case the root of the problem is bad zshape. Typical zsape = xshape + yshape 1.
