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, or scalars contained in two multidimensional arrays, with automatic virtual array expansion (AX) enabled. AX allows you, for instance, to...
Because the matrix multiplication is associative; the product can be carried with different order, leading to the same result up to round-off error, MMTIMES usings "optimal" order of binary product to reduce the computational effort...
This directory contains MATLAB functions for the fast multiplication of a Toeplitz matrix times a vector. By using these routines you can avoid storing the entire matrix (using two vectors of lenght n rather than a matrix of size n*n), and also...
This submission defines a generic class of matrix-like objects called MatrixObj and a subclass called DataObj. Objects of the class are capable of behaving as matrices, but whose math operators (+,-,*,,.*,,etc...) and other methods can be...
Neodynamic ThermalLabel SDK for .NET is a lightweight class library (DLL) that lets you to design barcode labels and print them to Zebra Thermal Printers (ZPL or EPL) by writing just pure .NET code in VB.NET or C#. ThermalLabel SDK can be used for...
This recipe adapts the infix operator trick from http://code.activestate.com/recipes/384122-infix-operators/ to give the appropriate behavior with numpy arrays, so you can write A *dot* B for np.dot(A,B)
UPDATE A solution to the...
ThermalLabel Editor Add-on is a first-class barcode label designer component for .NET Windows desktop apps (WinForms & WPF) which empowers your own apps by providing an end-user visual label editor! It features visual aids for the creation of...
It first transforms to patient coordinates and then to the second coordinates. Both dicom image sets should have the same localizer while scanning. It takes two inputs: dicominfo structures (taken by dicominfo mmand) of two image sets. The...
The main function included in the attached file is called FRAME. The algorithm implemented in this function can be useful in motion analysis (biomechanics, bioengineering). When you know the 3-D position of at least three non-collinear...
Using 'reduce' and 'map', this code shows how a matrix vector multiplication can be reduced to a single loop.
A more short code for generating a random matrix A of (1,-1),no loop
A small snipet of code to find the determinant of a mtrix of any order.Input must be a list like [[1,2,3],[4,5,6],[7,8,9]] (for a matrix of order 3). Works fine.
The zip file contains 1. A 128x256 Regular (3,6) H matrix (if you need to simulate other codes, need to write your own code for generating those parity check matrices). The file '128x256regular_v6.mat' is for those using Matlab 6.5. 2....
G=CACODE(SV,FS) G is a matrix with 1023*FS columns with a row for each PRN desired. SV is a vector containing PRN numbers to be generated, from 1 to 37. FS is the number of samples per chip desired in the code sequence. (Default=1).
this code will require the user to specify the size of the H matrix wanted to be generated.
The code uses array indexing to implement shifting of the matrix. It is about 2.5 times faster than using interp2 with 'nearest neighbor' option for shifting of the matrices. Inspiration for optimized array indexing comes from a snippet on...
The program can produce the parity check matrix of DVB-S2 LDPC with the size 8100*4050, and 1/2 code rate. Copyright (C) Yang XIAO, Beijing Jiaotong University, June 22, 2010, E-Mail: yxiao@bjtu.edu.cn. Current Version Published:...
This simple code, generates the ECOC matrix for both dense and sparse schemes. This simple code, generates the ECOC matrix for both dense and sparse schemes. It is more efficient in terms of speed than previously seen Matlab files to generate...
This function converts an MATLAB 2-dimensional array (matrix) which can be numerical or a cell array, into proper formated LaTeX code. This utility is actually the GUI representation of M.Koehler matrix2latex code.
A C++ matrix class for creating matrix objects and easily performing elementary operations between matrix objects including addition, subtraction, multiplication, transposition, and trace. |
