This simple function tests the null hypothesis that two variables are equally linearly correlated with a third variable when all three sets of observations were derived from the same "individuals" (i.e., a repeated measures/paired observations design).

NCHOOSE - all combinations of the elements of a set W = nchoose(S) returns all possible combinations of one or more elements of the set S. In total there are 2^N-1 combinations, where N is the number of elements in S. W is a cell array: each cell holds one of these combination (as a row vector).

The BaFigExPro package provides an automatic method to export Matlab figures, with optional uniform styling. Several input/output folders can be given in a single call. The routine works both for Windows and Linux (tested on Matlab 6.5 and 7.x). The package is generally used to: - make uniform figure styling with batch processing.

The Expectation-Maximization algorithm (EM) is widely used to find the parameters of a mixture of Gaussian probability density functions (pdfs) or briefly Gaussian components that fits the sample measurement vectors in maximum likelihood sense [1]. In our work, the expectation-maximization (EM) algorithm for Gaussian mixture modeling is improved via three statistical tests: a) A multivariate normality test, b) a central tendency (kurtosis) criterion, and c) a test based on marginal cdf to find a discriminant to split a non-Gaussian component.

There have been lots of cases where I'll want to look, in a specific order, at subjects in a larger set. Setdiff Intersect and Union are the exact operations I want, but unsorted. I coded up Unique just for good measure. These are relatively rough m-files, w/ little or no help functions, but they're very simple and identical to the built-in Matlab functions, just without sorting.

This filter could be extended into a 2D image smoothing filter. The kernel can be switched easily. This is a program to test how a gaussian filter works on a set of 1-D data a e.g. a=[1 10 1 10 1 10 1] --- use this as input or use your own 1D data This example uses a gaussian filter extracted from wikipedia: kernel = [0.

Subplot tends to leave a lot of empty space around the axes. Tight_subplot allows to adjust the spacing between the axes as well as the margins around the axes. For example: ha = tight_subplot(3,2,[.01 .03],[.1 .01],[.01 .01]) for ii = 1:6; axes(ha(ii)); plot(randn(10,ii)); end set(ha(1:4),'XTickLabel',''); set(ha,'YTickLabel','').

PCG Preconditioned Conjugate Gradients Method is a replacement of the standard built-in PCG code. Two new options are implemented: 'flex' and 'null'. The 'flex' option changes the standard PCG algorithm into the flexible one. It allows using sophisticated preconditioning, not limited to the traditional fixed SPD preconditioners, as required by the standard PCG.
