用matlab追迹子午光线，处理像差问题(Meridian ray tracing using matlab to deal with the problem aberration)

matlab excel compiled programming

This program compute Fourier,Cosine & Sine Transforms

THIS PROGRAM USES PULSE EXPANSION FOR THE ELECTRIC CURRENT MODE C AND POINT-MATCHING FOR THE ELECTRIC FIELD AT THE CENTER OF EACH C WIRE SEGMENT. C C DELTA-GAP FEED MODEL IS USED IN BOTH FORMULATIONS. IN ADDITION, C MAGNETIC-FRILL GENERATOR IS AVAILABLE IN THE POCKLINGTON S C INTEGRAL EQUATION.

本模型是根据国外一篇期刊论文的思想搭建起来的二极管钳位三电平逆变器的异步电机直接转矩控制的仿真模型，比较很精确(This model is based on a journal paper abroad thought to build up a diode clamped three-level inverter direct torque control of induction motor, a simulation model of comparison is very accurate)

说明：  Hu不变矩基础实现，七个不变矩，仅计算不变矩，未计算相似度(Hu imdidndaidndansjncisancicn)

Time-frequency representations with fixed windows or kernels figure prominently in many applications, but perform well only for limited classes of signals.

LMD（局域均值分解）程序。与经验模态分解的思想相近，是一种较新的处理非平稳信号的方法，但LMD方法的端点效应更小些。(LMD (local mean decomposition) program. And empirical mode decomposition similar idea, is a relatively new method for non-stationary signals, but the end effect is much smaller LMD method.)

介绍了radon变换原理，举了些例子并进行了实现(radon transform and some examples)
