Multiplication Array

This simple PHP example shows how to read a text file into an array, with each line of the file as a seperate element.

search array find in array script searches an array to find a specific value.

Using 'reduce' and 'map', this code shows how a matrix vector multiplication can be reduced to a single loop.

3D Array Factor of a 4x4 planar array antenna calculated using general formulas and then plotted in 3D format."AB" shows the excitation amplitude of the elements and "AB_phase" shows their phases.Elements are placed on the x and y axis and element factor is ignored. The code can easily be...

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...

UTC time (universal time convention) is used in ANSI-C standard for defining time. This is measured in seconds since 1970, at the Prime Meridian.The UTC2Datenum_array function takes a M x 1 array of UTC time values and converts it to a M x 1 array of Matlab serial Time values.This code is derived...

Accepts a 1-dimensional struct array (in the format 1xn) and converts it into a cell array. The first row of the cell array has the struct's field names in each column; the data from each of those fields for each entry in the struct array appears in subsequent rows. The idea is to make it easy to...

Inverse every 2D matrix slice (the first two dimensions) for multi-dimensional array M: M(:,:,p,q,...) * X(:,:,p,q,...) = repmat(eye(m),[1,1,p,q,...]),where input M is a N-D array (m x m x [p x q x ...]), for all possible m=1,2,3,...and optional higher dimensions. Output X array has the same size...

This function writes a cell array into a CSV-file.It works with empty cells, numeric, char, string and logical cells. One array can contain all of them, but only one value per cell.CSV-files can then be read by Excel, so you don't need DDE or ActiveX.

This code converts a Galois Field array created using GF(2^m) for a given primitive polynomial into the 'exponential' notation, which you can use with gfrepcov() to binary if you wish.Uses the gf2dec() function internally.Example usage:>> genpoly = rsgenpoly(15,11)genpoly = GF(2^4) array....

Used to perform B*M or M*B with B a block diagonal matrix, B is stored as a cell array (call it C) with each element a matrix as a block of B, such that B = blkdiag(C{:}).This speeds up the multiplication when B is large and also allows the operation to take place when B could not fit in the...

MULTIPROD is a powerful, quick and memory efficient generalization for N-D arrays of the MATLAB matrix multiplication operator (*). While the latter works only with 2-D arrays, MULTIPROD works also with multidimensional arrays.MULTIPROD performs multiple multiplications between matrices, vectors,...
