Arrays

It can establish a connection to a MySQL database server host, execute SQL queries and retrieve the results into arrays. The identifier of the last inserted record can also be retrieved, and whether a given table exists can be checked. Requirements: - PHP 4 or higher

This script is a groupby function for arrays. Given a list of arrays and a `key` function, it will group each array based on the value of `key(args[0])`. The returned arrays will be two dimensional. The size of the first dimension is equal to the number of groups, and the size of the second...

phpArmory is a PHP class library that can easily fetch and unserialize World of Warcraft Armory XML data into structured associative arrays. The phpArmoryCache class fully supports both flat files and mysql caching of any and all "fetch" functions.

GDGraph for PHP is a PHP class that gives it the ability, while using GD, to build dynamic line, pie and bar graphs given some preformed arrays. The way this class works, is that it will return an online PNG image to your browser after any of it's functions (bar_graph, pie_graph or line_graph are...

This is an old program (1.999) that I have written for understanding radiation patterns of antennas. Basically I was looking for the relationship between interference diagram (Fourier transform of ilumination, usually called Array Factor) and 3D radiation pattern of the Array. For that reason, it...

This function is a more robust and improved version of my previous submission, matchingpursuit.mThis function computes the projection of a given input vector or matrix onto a "dictionary" of other vectors or matrices using a matching pursuit algorithm. Users may input a vector to be synthesized,...

STREAMCOLOR(X,Y,U,V,STARTX,STARTY,VMAG) or STREAMCOLOR(X,Y,Z,U,V,W,STARTX,STARTY,STARTZ,VMAG) creates streamlines from 2D or 3D vector data U,V,W. The arrays X,Y,Z define the coordinates for U,V,W and must be monotonic and 3D plaid (as if produced by MESHGRID). STARTX, STARTY, and STARTZ define...

Dynamical analyses in engineering often require inertial properties of complex shapes such as polyhedra. The volume, the first moment of volume and the second moment of volume of a general solid can be computed by V = Integral( dVol ), VR = Integral( R*dVol ), VRR = Integral( R*Rd-deOao*dVol )....
