- JLAB: Matlab freeware for data analysis
pop
JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute.
Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets; a systematic way of dealing with datasets having components of non-uniform length; tools for fine-tuning figures using compact, straightforward statements; and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

ICALAB for Signal Processing - ICALAB for Signal Processing is package for MATLAB that implements many efficient algorithms for ICA (independent component analysis) employing HOS (higher order statistics), BSS (blind source separation), SOS (second order statistics), LP (linear prediction), and BSE (blind signal extraction) employing various SOS and HOS methods. After some data preprocessing, this package can also be used for MICA (multidimensional independent component analysis) and NIBSS (non independent blind source separation).

environment called MATLAB. This toolbox will be useful to researchers that are interested in how the auditory periphery works and want to compare and test their theories. This toolbox will also be useful to speech and auditory engineers who want to see how the human auditory system represents sounds. This version of the toolbox fixes several bugs, especially in the Gammatone and MFCC implementations, and adds several new functions. This report was previously published as Apple Computer Technical Report #45. We appreciate receiving permission from Apple Computer to republish their code and to update this package.

Features a unique program to estimate the power spectral density. The
spectrum containing all significant details is calculated from a selected time series model. The model type as well as the model order are determined automatically from the data, using statistical selection criteria. Robust estimation algorithms and order selection criteria are used to obtain reliable results. Unlike in FFT analysis, where the experimenter has to set the amount of smoothing of the raw FFT, the right level of detail is assessed automatically using the data only.

the toolbox lies in the modelling and the extraction of sets of parameters describing the four-dimensional data, allowing easy interpretation and identification. All of the methods have low level modelling functions and a GUI interface for easy access to the data and modelling results. The toolbox includes data import routines, a set of preprocessing steps and a set of data modelling strategies. It is important to realize that no single model can grasp all the features of the data. Each of the models have their own contributions, and the assumptions underlying the models are very different in nature.
