Basic implementation of the Phase Spectrum Compensation (PSC) [1] method for single channel speech enhancement is included, along with a demo that illustrates its usage.References:[1] A.P. Stark, K.K. Wojcicki, J.G. Lyons and K.K. Paliwal, "Noise driven short time phase spectrum compensation...

This function solves the system of linear equations A*x=b, using the simplest form of the SQMR algorithm without look-ahead, where A is square and symmetric.SQMR is an adaptation of the general nonsymmetric QMR method to exploit the symmetry of the matrix A. With SQMR, one can use symmetric...

Converts normally distributed z-statistic to one- or two-tailed p-valueby integrating the standard normal pdf. If no "tails" value is specified, z2p computes the two-tailed value by default. The output p is the same size as z, which can be a scalar, vector, or matrix. Inputs:z: normally...

H = TRIPLESTEST(X) performs the non-parametric triples test for symmetry (skewness) of the null hypothesis that the data in X comes from a symmetrical distribution with an unknown median. The test involves the examination of subsets of three variables from X (triples) to determine the likelihood...

This m-file performs the Bowker's test for symmetry. It is an extension of the McNemar test to a KxK situation. There are now K response categories for the two dependent samples.The null hypothesis is that the probabilities in the square table satisfy symmetry or that there is no sifnificant...

We can exploit the symmetry of a real, positive definite, symmetric matrix by using the Cholesky decomposition to compute the inverse.The built-in MATLAB inv function uses LU decomposition which requires extra pivots and operations. Rarely does one actually need to compute the inverse of a matrix...
