Probability Density Function

Wigner3j(j1,j2,j,m1,m2,m) returns the Wigner 3j-symbol, where j1, j2, j, m1, m2, and m are half-integers. Physically, the Wigner 3j-symbol is closely related to the Clebsch-Gordon coefficient , the square of which is the probability that a system of two particles with angular momentum j1 and j2...

MEYERFUN Calculates Pd for non-coherent pulse integration. It uses the equations in the appendix of "Radar Target Detection-Handbook of Theory and Practice" by Daniel P. Meyer and Herbert A. Mayer to calculate the threshold and probability of detection for the five standard Swerling cases....

This scripts shows you how to obtain the name of a method or a function from within the running method/function.

This function can extract a inner function from a class or a function. It may be useful when writing a unit test code.


Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script defines a simple but useful class that emulates a function to gracefully permit latent assignment. In other words, you can use the emulating class as a valid function in assignments with the ability to later associate a function to perform the actual operations.

This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is :1. you can call this function directly in your script, you will have to pass only the value of 'a' (length of code is 2 ^ a)2. this function can return you both the...

This GUI can be used by entering 'nu' at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot over a user defined range. The function's integral can be evaluated over a user defined range by...
