- Generic Signal Class
- License: Freeware
- Price: 0.00

A signal object (an object of class "signal") is a set of data in an one dimensional array, combined with information about its sample rate, starting time and other useful infos. A number of methods makes it easy to generate and modify signals. "signal" is used and tested for considerable time in the aim-mat project.

- Dynamic Time Warping
- License: Freeware
- Price: 0.00

If you pass in 2 vectors it returns the unnormalized distance between the vectors, the accumulated distance between them, the length of the warping path (the normalizing factor), and the warping path points. To compare 2 vectors A and B call: [Dist,D,k,w]=dtw(A,B) Dist is the unnormalized distance D is the accumulated distance k is the length of the warping path (the normalizing factor) w is a matrix containing the points along the warping path.

- decimation matrix
- License: Freeware
- Price: 0.00

This function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal... D = decimmtx(x,N) decimates the given signal by a factor of N. [D,y] = decimmtx(x,N) gives D as well as the decimated signal y.

- DSP Code Verification using UDP
- License: Freeware

In this document I show how to verify the functionality of your DSP code via processor in-the-loop (PIL) co-simulation using Simulink?s UDP (user datagram protocol) blocks. These blocks are a new addition to the R2006b release of Simulink. This example is an extension of a previous example which was based on using Texas Instrument?s RTDX (real-time data exchange) instead of UDP.

The signals presented here can be used in demonstrating how the signal varies when the operation is made on either independent variable or dependent variable. The parameters can be varied to have a feel of the variation. Example(1): rect(1,2) plots the rectangular signal of amplitude 1 and a width of 2.
