Computes the autocovariance of two columns vectors consistently with the var and cov functions. in matlab

The following Matlab project contains the source code and Matlab examples used for computes the autocovariance of two columns vectors consistently with the var and cov functions. . autocov computes the autocovariance between two column vectors X and Y with same length N using the Fast Fourier Transform algorithm from 0 to N-2.

Autocorrelation pitch detector in matlab

The following Matlab project contains the source code and Matlab examples used for autocorrelation pitch detector. This MATLAB exercise implements a pitch period detection algorithm using the modified autocorrelation method with a specified center clipping threshold. It analyzes a designated speech utterance on a frame-by-frame basis, using a center-clipped, modified correlation analysis method.

Dft Matlab Code

discrete Fourier transform (DFT) converts a finite list of equally spaced samples of a function into the list of coefficients of a finite combination of complex sinusoids, ordered by their frequencies, that has those same sample values. 

Compute n x n dft matrix in matlab

The following Matlab project contains the source code and Matlab examples used for compute n x n dft matrix. % dftmat = DFT matrix of order N x N; % N = Order of the matrix % computes the DFT matrix of orer N x N; % DFT matrix is a n x n matrix defined as Wn=[(Wn)^km] % Wn=exp(-j*2*pi/n) %Reference: Multirate Systems and Filter banks by P.
