In statistics, an expectation-maximization (EM) algorithm is a method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. EM is an iterative method which alternates between performing an expectation (E) step, which computes the expectation of the log-likelihood evaluated using the current estimate for the latent variables, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.

一个剪切波变化工具箱，里边程序很全，有范例，值得拥有(A shear wave change toolbox, inside the program is full, there are examples worth having)

This matlab code is intended to demonstrate the physical significance/interpretation of the elements of diagonal matrix in Singular Value Decomposition (SVD). Here, multiple rows of a BIG matrix is gradually being filled with ones which means the information content is being reduced. Now, the eigenvalues and their 1st and 2nd derivatives are plotted.

EasyMod is a MatLab/Scilab toolbox for teaching modal analysis. It provides a set of functions allowing to establish the identification of modal parameters and these validation. Nowadays, circle-fit, line-fit and least square complex exponential methods are implemented. In addition, some relevant functions are offered in order to complete a modal analysis: operations on the frequency response function (FRF) , generation of FRF from mass, damping and stiffness matrices, MAC (modal assurance criterion) and modal collinearity
