/* /////////////////////////////////////////////////////////////////////////////
// Name: ippsPeriodicity
// Purpose: Computes the periodicity of the input vector. In typical
// applications, the input vector is the magnitude-squared of the discrete Fourier
// transform of speech. The periodicity is defined as the periodic sampling of the
// input vector that preserves the most energy.
//
// The period is defined as P such that
// P = argmax_(p) sum_n[ x(b + np) ]/N
// where Pmin<=p<=Pmax, 0<b<p, N<=MAX_HARMONICS, 0<n<N
// N is the smaller of the number of harmonics in the input vector
// for a particular period (p) or MAX_HARMONICS
//
// Using the N,P values obtained above, the periodicity is calculated as:
// periodicity = sum_n[x(k+nP)] / sum_n2[x(n2)], 0<n<N, 0<n2<len
//
//
// Arguments:
// pSrc - pointer to the input vector containing non-negative entries
// for, e.g. magnitude spectrum values
// len - number of elements contained in the input vector
// maxPeriod - maximum period to search
// minPeriod - minimum period of search
//
// periodicityQ15 - normalized sum of the largest harmonic sampling
// period - period in sample that provided the maximum-energy harmonics
//
// Returns: ippStsNoErr - No Error.
// ippStsBadArgErr - Bad Arguments.
//
// Notes: none
