Math Function

A recursive function to get permutation of a list script allows you to make permutation on a list of objects. The script does not work on repeated items in the list. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script contains two classes that show two styles of function composition. The difference is only when the second function (g) returns a tuple. compose function passes the results of g as a tuple, mcompose treats it as a tuple of args to pass along. Note that extra args provided to... Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script contains a function that finds out the gcd(a,b)(great common divisor of a and b) as a linear conbination of a anb b, ax by=gcd(a,b). Platforms: Windows, Mac, *nix, Python, BSD Solaris

JavaScript or cookies are not required for this plugin to function correctly.It uses a special encryption function; the result of the question is being passed via a hidden field. The result is being compared with the value entered by the visitor – after encrypring this value as... Platforms: Windows, Mac, *nix, PHP, BSD Solaris

This simple m-file plots the Soft Handover probability as a function of the Soft Handover Threshold value used in the UTRA Soft Handover Algorithm. The relationship has been dertived by taking the ratio between the Cell area where Soft Handovers are enabled and the total Cell area. Platforms: Matlab

VIDEO TUTORIAL: Serial communication (TX and RX) using SERIAL Matlab function. For Bluetooth and RS-232 devices applications. (Narration in Spanish). Platforms: Matlab

To use this function just define a variable say var,var = pnseq(a, b, c);for a, b and c refer to the zip file Platforms: Matlab

The zip file contains functions to calculate an Ambiguity Function (XAMB), Upsampled and Interpolated Correlation (XCORRU), and Coherence Function (XCOH). A prefilter can be specified in each function to "sharpen" correlation peaks.XAMB calculates an estimate of the (cross-)ambiguity function. A... Platforms: Matlab

Because of the "erfc" function, the processing time is very small. Platforms: Matlab

A standard atmosphere function based on the 1976 Standard Atmosphere returns density, speed of sound, temperature, pressure, and viscosity for a given altitude input up to 86km.This function is designed to be useful for those designing and analyzing aircraft and has the following features that...

Designing a Controller and obtaining the Controller Function by rootlocuse method Platforms: Matlab

Program given here computes the discrete transfer function of a DC motor (Example taken in this case) using pseudo inverse technique. The input and output data for any single input single output system can be used to find out the discrete transfer function of that system. Platforms: Matlab

Writes to file a sorted list of MATLAB functions for all MathWorks products installed on the machine (that the function is executed on). Denotes which functions are built-in to help with syntax highlighting. Platforms: Matlab

Computes the nth moment mean of a function (needs more implentation).m = moment(x, y, n)m = nth moment of yx = domainy = datan = nth moment == 1 by defaultm = int(x^n * y) / int(y)where int is integral over all x integral is calculated using trapezium rule Platforms: Matlab

The function shows the text string S and prompt the user for an input value guaranteing that the input value is numdoTeric.When the value is not numdoTeric the function gives an error mensage and prompts for a new value until it is numeric. Platforms: Matlab

PHP Function Reference provides fast lookup of information about the PHP web programming language. Features * Offline access to the same documentation found on PHP.net * Extensive cheat sheet of common PHP language syntax * Interactive date string formatter * Favorites list * 1-click... Platforms: Mac

Math::GMPq is a bigrational Perl module utilising the Gnu MP (GMP) library. Basically this module simply wraps all of the 'mpq' (rational number) functions provided by that library. The documentation below extensively plagiarises the GMP documentation (which can be found at http://gmplib.org).... Platforms: *nix

Math::Geometry is a Perl module that implements classic geometry methods. It should be considered alpha software and any feedback at all is greatly appreciated. The following methods are available: vector_product. Also known as the cross product, given two vectors in Geometry space, the... Platforms: *nix
