COMPOSITE SIMPSON's method for numerical calculations and analysis exercises of Numeric Integration. f function is given in terms of a symbolic variable x and as aninline function. E.g., inline('x^2+2*x-2'). Also, if the function f is trigonometric function, the 4th argument can be entered... Platforms: Matlab

The code implements the shooting method by means of the Runge-Kutta method of 4th order and the interval bisection method. There is the graphical interface too. When the differential equation is inserted in terms of the standard mathematical notation (no in MATLAB code), the programme create the... Platforms: Matlab

This is a simple gui application that used gaussian quadrature inegration based on index=1-3. It can be easily extended to higher order of indices for better accuracy. For more information visit:http://en.wikipedia.org/wiki/Gaussian_quadrature Platforms: Matlab

The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with reference to given cluster. Platforms: Matlab

The Expectation-Maximization algorithm (EM) is widely used to find the parameters of a mixture of Gaussian probability density functions (pdfs) or briefly Gaussian components that fits the sample measurement vectors in maximum likelihood sense [1]. In our work, the expectation-maximization (EM)... Platforms: Matlab

Generate Gaussian or Laplacian pyramids, or reconstruct an image from a pyramid. Contains a demo script doing image blending using pyramids. The function is more convenient to use than the Matlab function impyramid. Platforms: Matlab

This code uses conjugate gradient method to solve the linear systemAx= b, where A is symmetric and banded. A is first stored in acompactstorage mode, using the function "compactstorage", and thenconjugate gradient method is applied to the compactly stored matrix.Input: A, initial guess x, vector...

In this program I will find He atom ground state energy using Hartree-Fock method. My program based on an algorithm which is written in Thijjsen's Computational Physics books chapter 4. Platforms: Matlab

This code illustrates Bartlett method for a simple signal (sum of three sinusoids). This code allows user to change to length of each pieces (sub sequence).For example in the code LS is the term which gives length of each piece. Here it is 30 and signal length is 65. So signal will be chopped... Platforms: Matlab
