Derivative Of A Function Calculator

This module uses a visitor's IP address to identify the geographical location (country) of the user. The module makes this determination and stores the result as an ISO 3166 2-character country code in the Drupal $user object, but otherwise has no effect on the operation of your site. The intent...

This one line function adds up the ascii values of a string and returns the total as a checksum. Also included is a variation which returns the checksum mod 256 (so it can be used as a single byte).The same technique can be used to add up a list of numbers, or to return the average of a list...

In Graph Theory it is often required to find out all the possible paths, which can exist between a source node and a sink node.So this function returns a all such possible paths, in a matrix format.INPUTS:1. 'X' Matrix: Form a Nx2 matrix, where N is the total number of 'Edges'. This Matrix will...

This package includes files for modelling nonlinear dynamic systems using a recurrent generalized neural network. The learning scheme uses the complex method of nonlinear nonderivative optimization, thereby avoiding the problems of computing the derivative of an infinite impulse response filter...

DFT transforms one function into another, which is called the frequency domain representation, or simply the DFT, of the original function (which is often a function in the time domain). But the DFT requires an input function that is discrete and whose non-zero values have a limited (finite)...

This function will return true if the first input structure contains the field in the second input string and in turn that field has the field given in the third input string and so on. This allows A.b.c = 2; to be checked as:isfieldRecursive(A,'b','c')ans =1Which would return false if either b...
