Parameters

dstLen   Specifies the number of elements in destination buffer(this will be the length of auto-correlation)
pDst   Pointer to a destination buffer.
pSrc   Pointer to a source buffer.
srcLen   Specifies the number of elements in source buffer

Description

Estimates normal, biased, and unbiased auto-correlation of a vector and stores the result in a second vector.
