Listing of Communication in Scripts

This simulator creates a source to microphone impulse response in complex room environments. It's based on the image method by Steven Boll'79. You may select frequency dependent wall coefficients and orientation dependent sources. Please refer to the tutorial.

This file contains MATLAB functions, m-files, that do Huffman coding and arithmetic coding of integer (symbol) sequences. Complete coding may be done by calling an easy to use main program (or main function), where input argument is the sequences you want to compress and the output is the compressed bitstream, as a vector of bytes.

This basic model shows you how to acquire live data from an Agilent oscilloscope into Simulink. This model was developed for the Agilent 6000 series oscilloscope but may work with other Agilent scopes with little or no modifications. I welcome submission reviews below to let us know whether you got it working with your specific Agilent scope.

SSA generates a trayectory matrix from the original series by sliding a window of length L. The trayectory matrix is aproximated using Singular Value Decomposition. The last step reconstructs the series from the aproximated trayectory matrix. The SSA applications include smoothing, filtering, and trend extraction.

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself.

STL_Import is a tool designed to import into MATLAB both binary and ASCII STL files. This script is mainly a collage between file exchange file id 22409 and 3642, plus some other features that can be considered new.

CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h).
