利用Matlab编程实现主成分分析,从数学角度来看，这是一种降维处理技术(Using Matlab programming principal component analysis, from a mathematical point of view, this is a dimension reduction process technology)

using servo characteristic equations,transfer function is derived by taking laplace

Key to the book:C++ HOW TO PROGRAM 7th, chapter 7.

Fast Gaussian Convolution with Recursive Filtering.

基于matlab的有限元程序源代码，希望大家喜欢(Based on the finite element program matlab source code, I hope everyone likes)

lte parameters like ofdma ,sc fdma,block source bandwidth,channel types

二维FDTD仿真高斯脉冲的传播，设定了PMC边界条件，并且可以自动生成Ez、Hx和Hy的.avi文件播放。(Propagation of two-dimensional FDTD simulation Gaussian pulse, set the PMC boundary conditions, and can automatically generate Ez, Hx and Hy .avi files playback.)

主要是matla中的snake算法的一些模板套路，像是snakedeform、snakedisp、gaussianMask等(The snake is mainly matla some templates algorithm routines, such snakedeform, snakedisp, gaussianMask etc.)

遗传算法函数initializega，2010a以后需要手动载入。(The Genetic Algorithm function of Initializega.)

Implements the 1st and 2nd order Gaussian derivative steerable filter in matlab.The oriented first order derivative can be obtained by taking the dot product of a unit vector oriented in a specific direction with the gradient. The basis filters are the partial derivatives of a 2D Gaussian with respect to x and y
