for entropy H = entropy(S) this command will evaluate the entropy of S, S should be row matrix H = entropy([X;Y;Z]) this command will find the joint entropy for the 3 variables H = entropy([X,Y],[Z,W]) this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies Please validate this function before using it.

In this implementation of tracking a ball, we will track a live ball using Kalman filter. The tracking will switch to autorun mode when the sight of the ball is lost and Kalman will estimate the motion based on it's previous states There are two models.

This function searches the interior of a signal in an attempt to find a segment that may be used in order to make the signal quasi-periodic. This can be used to reduce the influence of end effects on analyses such as the Hilbert Transform, the Wavelet Transform, the Hilbert-Huang Transform and EMD, or Hilbert Vibration Decomposition.

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits. QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput. I hope this will be helpful for students of wireless communication.

alculate the normalized partial energy sequence (NPES) for a given signal vector X. If a particular transform is capable of capturing the key features of a signal in few coefficients, the NPES will approach unity for relatively quickly.

Here I don't provide any code (yet), but I'd like to hear your voice of feedback about what you fellow Matlab developers think. The more you express enthusiasm, the sooner there will be actual code available for download. The more you criticize and the more constructive suggestions and comments you post the better it will be.

This toolbox includes a complete set of blocks implemented in the Simulink environment, which allows designers to perform time-domain behavioral simulations of switched-capacitor sigma-delta modulators. The proposed set of blocks takes into account most of the SC sigma-delta modulator non-idealities, such as sampling jitter, kT/C noise and operational amplifier parameters (white noise, finite dc-gain, finite bandwidth, slew-rate and saturation voltages).

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.
