Seismic Signals

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...

Usage: I=mi(A,B), where A and B are equally sized images/signals.Function hist2 (included) is used to determine the joint histogram of the images/signals.Assumptions: 1) 0*log(0)=0, 2) mutual information is obtained on the intersection between the supports of partial histograms.Example (in...

The function introduces the implementation of fft and ifft in filtering and cleaning of signals.The function plots1. the original signal,2. its transform,3. the reconstructed (filtered) signal.You can control the filtering by giving your parameters.Comprehensive help is included (>>help fftf).The...

Given an open Simulink model, Log_Signals allows you specify a list of signals in the diagram that you want to log. Optionally, there are flags that let you select "all" or "none".This script just saves you the trouble of digging through the diagram to find a particular signal.

One Should ALWAYS Be Running a Prudence Index Options System Trade! I left a lot of money on the table by being lazy and not running every single trade before. And the system is so laid back. The big money seems to come a lot easier on a big trend system such as this. Since these are big trends...
