Matrix Equation

The method uses finite differences to solve Laplace equation and matrix inversion to solve the resulting system of linear algebraic equations. The rectangular plate has both dimensions set equal to unity. Each dimension is discretized and the total number of nodal points is equal to 29*29. To... Platforms: Matlab

UC Matrix is an extension of the UC Affiliate2 module. I allows you to handle cases where the matrix of affiliates needs to be forced. For instance, you may want to have a maximum of 2 people under each affiliate (called a binary matrix.)FeaturesThe following are the features I planned to... Platforms: PHP

Simple example of the use of the FMINSEARCH function to fit the blackbody equation to the emission spectrum of an incandescent body for the purpose of estimating its color temperature and emissivity. fitblackbody.m is the fitting function.

This is a small example code for "Steepest Descent Algorithm". It implements steepest descent Algorithm with optimum step size computation at each step. The code uses a 2x2 correlation matrix and solves the Normal equation for Weiner filter iteratively.Reference:Adaptive Filter Theory 3rd... Platforms: Matlab

In the programs, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure. All... 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

Two mass variable equations with "Aerospace 3Dof Simple Variable Mass Blockset" are compared in a 1Dof frictionless environment. Initial conditions are given in Model Callbacks.Results showed that "Aerospace 3Dof Simple Variable Mass Blockset" uses the incorrect equation. 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
