//               steps are taken for large values where the function is fairly

//  Name:           ippsPeriodicityLSPE
//  Purpose:      Estimates the periodicity and period of the input frame.
//                 The core algorithm used is the least-squares periodicity estimator as
//                 described in Section 4.1 of the paper:
//                   R.Tucker,"Voice activity etection using a periodicity measure",
//                   IEEE Proceedings-I Vol. 139, No. 4, August 1992
//
//                 The approach is to compute the normalized periodicity measure (R1) for
//                 all values of possible pitch periods in samples (Pmin <= P0 <= Pmax). The
//                 maximum value of R1 obtained is the estimated periodicity of the input frame
//                 and the corresponding period (P0) is the pitch period in samples of the input frame.

//                 this function is as follows:

//  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

//
//                   Using the N,P values obtained above, the periodicity is calculated as:
