一个基于的MATLAB的计算器GUI例程，适合初学者学习。(Based on MATLAB the calculator GUI routines, suitable for beginners to learn.)

matlab 简介滤波程序代码，不错的哦，分享给大家看看(matlab lvbochengxu，hahhahahhhhhhhhh)

pso-svm very useful, we want to be useful.

菲涅尔衍射。仿真圆形光圈的菲涅耳衍射，显示菲涅耳衍射图样的模值。(Fresnel diffraction simulation of circular aperture Fresnel diffraction, display mode value of the Fresnel diffraction pattern.)

Locality Preserving Projections(LPP),局部保留投影，可以找出高维空间中的数据在低维空间中的投影，并保留了数据之间的相关性(Locality Preserving Projections (LPP), partial retention projection, you can find the data in high-dimensional space in a low dimensional space projection, and retains the correlation between data)

matlab绘图的一个程序，程序不是很长 但比较经典 (very good)

pfc boost converter single phase

应用matlab进行模式识别，主要针对图片中的数字进行识别，识别效率高(Application matlab pattern recognition, digital picture identification)

双线性系数变换子程序 《数字信号处理教程——MATLAB释义与实现》 双线性系数变换子程序(Bilinear coefficient transform subroutine " digital signal processing tutorial- MATLAB Interpretation and Implementation" bilinear coefficient transform subroutine)

说明：  一个计算拉个朗日插值很好的程序，绝对正确无误。(A calculation of long pull on a good interpolation procedure, is absolutely correct.)
