Linear equations of both full rank and deficient rank in matlab

The following Matlab project contains the source code and Matlab examples used for linear equations of both full rank and deficient rank. lineq is the main program, help message for lineq function [homsol,spsol]=lineq(a,b) % solve linear equations a*x=b; % [homsol,spsol]=lineq(a,b); % lineq(a). where homsol are solutions of corresponing homogenous equation, spsol is the special solution of a*x=b.

Steepest ascent/descent is a simple and efficient optimization method ... in matlab

The following Matlab project contains the source code and Matlab examples used for steepest ascent/descent is a simple and efficient optimization method ... . This m-file provides a simple and efficient optimization method based on statistical design of experiments by the steepest ascent/descent procedure to predict points headed (hopefully) toward to optimum (maximum or minimum) for a first-order design.

New approaches to constrained optimization in matlab

The following Matlab project contains the source code and Matlab examples used for new approaches to constrained optimization in matlab. M-files accompanying the webinar titled "New Approaches to Constrained Optimization in MATLAB" held on November 05, 2005 These files provide what you need to run the two demos: 1) The first demo is a demonstration of bound constrained optimization of non-smooth objective function using GA and also using a Hybrid function (using GA with another optimization solver).

This file generates cos and sin function using cordic algorthm in matlab

The following Matlab project contains the source code and Matlab examples used for this file generates cos and sin function using cordic algorthm . Usin recursive algorithm CORDIC this model generates the Cosine and Sine Function of a given angle. You must click over "Pulsa Aquí" block to put the angle also establish themax error in the simulation. Just Unzip the files

Cholesky factorization of the hilbert matrix of order n in matlab

The following Matlab project contains the source code and Matlab examples used for cholesky factorization of the hilbert matrix of order n . The Hilbert matrix is extremely ill-conditioned, hence cannot be factorized by standard algorithms. However, an analytic solution for its Cholesky factorization exists, which has not been included in the current MATLAB function library.

Newton corrector method for ordinary differential equation in matlab

The following Matlab project contains the source code and Matlab examples used for newton corrector method for ordinary differential equation. Thee purpose, 1. Speed up the convergence of correcting for each points (By newton method). 2. To find the first few points by this method instead of R.K. method. 3. To apply for higher order polynomial fitting.

Fill each row/column with a certain number of ones (n-ones) in matlab

The following Matlab project contains the source code and Matlab examples used for fill each row/column with a certain number of ones (n-ones) . NONES - fill each row/column with a certain number of ones (N-ONES)     A = NONES(V) creates a logical array A, in which each row/column     starts with zero or more TRUE entries followed by zero or more FALSE     entries, as specified by the elements of the vector V.

Gaussian curve fit in matlab

The following Matlab project contains the source code and Matlab examples used for gaussian curve fit. [sigma,mu,A]=mygaussfit(x,y) [sigma,mu,A]=mygaussfit(x,y,h) this function is doing fit to the function y=A * exp( -(x-mu)^2 / (2*sigma^2) ) the fitting is been done by a polyfit the lan of the data.
