Documentation Error, IPP 8.1 Volume 2, ippiGradientVectorScharr

The entry for ippiGradientVectorScharr shows a kernel identical to that shown for ippiGradientVectorPrewitt with sample weights of magnitude [1, 1, 1].  I believe for the Scharr gradient filter the kernel weights should be of magnitude [3, 10, 3].  This appears to be a simple copy/paste error in the document.

Thank you Dave,

it's really a copy/paste error - already fixed, will be updated on the web/in the package with the next IPP update/release.

regards, Igor
