说明：  这是我的课程设计，Kaiser窗FIR滤波器的Matlab实现，内附对结果的分析(This is my course design, Kaiser window FIR filter Matlab implementation, analysis of results included)

The matlab program is effective to be used for fringe processing. It contours strain distribution using an interferogram.

等参单元，用于弹性力学分析，数值积分法等(Isoparametric element，For elastic mechanics analysis, numerical integration method, etc.)

基于简单一元函数的遗传算法，通过使用Shdffield工具箱，更好的实现了遗传算法的每一步，并将其结果以图的形式展现出来。代码清晰易懂。(Functions of one variable based on a simple genetic algorithm, by using Shdffield toolbox to achieve better every step of the genetic algorithm, and the results show up in the form of graphs. Code is clear and understandable.)

matlab最基本的卡尔曼滤波的算法，最最基本的，就5步5句话，可以任意移植(matlab basic Kalman filter algorithm, the most basic, step 5 of the fifth sentence, can be transplanted)

说明：  图像特征提取，计算图像的7个Hu不变矩特征，matlab例程(Seven Hu invariant moments features of images)

matlab图像彩色处理，主要有三基色的调用，调整，以及图像的伪彩色增强(matlab image color processing, there are three primary colors of the calls, adjustments, and pseudo-color image enhancement)
