dftmat = DFT matrix of order N x N; N = Order of the matrix computes the DFT matrix of orer N x N; DFT matrix is a n x n matrix defined as Wn=[(Wn)^km] Wn=exp(-j*2*pi/n)Reference: Multirate Systems and Filter banks by P.P Vaidyanathan Pearson Education 1993 appendix A.6 Platforms: Matlab

This include a MEX-DLL file which is an implementation of R L Siddon's refined method by Jacob for the calculation of ray path integral in PET/CT system image reconstruction. This is based on Line Intersection Length model to calculate probability matrix elements. Inputs are the LOR number and a... Platforms: Matlab

This is the first part of the planned series for Model Predictive Control (MPC) tutorials.Dynamic Matrix Control is the first MPC algorithm developed in early 1980s. It is probably also the most widely used MPC algorithm in industry due to the fact that its internal model, the step response model... Platforms: Matlab

Input data is the Microsoft ExceldlT« file, where the table of nodes, table of elements, nodal external loads vector and boundary conditions are stored.After running the mabs3d.m file on the Command Window, the program calculates the stiffness matrix in local coordinates kiL (element i). Once... Platforms: Matlab

A set of blocks for manipulating 3x3 and 4x4 matrices. In versions of Simulink prior to R12, matrices were handled in row-major form, thus the need for special blocks to handle matrices. Although Simulink can now handle arrays as signals, some users may still find the row-major approach... Platforms: Matlab

This short tutorial illustrates basic numerical matrix computation in C. I encourage any comments from expirienced mex programmers for style improvement.This is a nice little function to demonstrate how you can interface MATLAB and C style matricies. There is some example code included showing... Platforms: Matlab

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must... Platforms: Matlab

Contains three matrix completion algorithms and a demo script for running them. Also compares against other matrix completion algorithms - Singular Value Thresholding and Fixed Point Iteration.Solves the following three optimization problems:min rank(X) subject to ||y - M(X)||_2 Platforms: Matlab

we can use any complete set of Eigenkets for basis of our hilbert spacewe can use |j1,j2,m1,m2> or |j1,j2,j,M>"clmatrix.m is use for building the transformation Matrix |j1,j2,j,M> = |j1,j2,m1,m2> Platforms: Matlab

The main file interpMatrix.m in this package creates a sparse Toeplitz-like matrix representing a regularly-spaced interpolation operation between a set of control points. The user can specify the interpolation kernel, the number of control points, the spacing between the control points, and... Platforms: Matlab

Implementation of Nicholas J. Higham's algorithm "Computing the Nearest Correlation Matrix - A Problem from Finance", 2002.http://eprints.ma.man.ac.uk/232/01/covered...S_ep2006_70.pdf Platforms: Matlab

DISTMATLATLON Computes distance matrix between list of coords in X and Y D = DISTMATLATLON(X,Y) for matrices X and Y, with columns [Lat Lon], returns the distance matrix where the (i,j)th entry is the distance between the i'th and j'th row of X and Y respectively. X and Y must have columns in the... Platforms: Matlab

Matrix decomposition using, e.g. the Cholesky decomposition requires the correlation matrix to be positive definite. That is, the eigenvalues must all be positive. In finance, this is rarely the case, and one often observes negative eigenvalues, or zero eigenvalues. These two functions do... Platforms: Matlab
