entropy function with matlab

用于图像去噪实验界面，包括小波去噪，中值滤波等，程序有MATLAB的gui界面，调试成功。(image denosing experiments, a good matlab interface .)

参数假设检验：对差异进行定量的分析，确定其性质，是随机误差还是系统误差. 为给出两者界限，找一检验统计量T，在H0成立下其分布已知.(Parameter hypothesis test: a quantitative analysis of the differences, to determine its nature, is random error or system error. Is given two boundaries, looking for a test statistic T, its distribution under the establishment of the H0 known.)

本工程实现了将三路合成的DSB信号用椭圆滤波器（低通，带通，高通）滤出； 其中的freqz函数，filter函数，fft函数都自己实现。 每种滤波器都分别用专门的函数分别写出，可以模块化。( This project will be three-way synthetic a DSB signal elliptic filter (low pass, band-pass, high pass) filter out Freqz function of which, the filter function, fft function. Each filter are, respectively, with a special function, respectively, to write, can be modular.)

用单球面透镜对日亚红色激光准直仿真，仿真以casio为模型(This is a model of RED LD focusing experient，basing on the casio product。)

基于matlab的源程序，用于绘制Rosslor方程的相图以及庞加莱截面(Based on matlab source program，used to draw phase diagram, poincare section of Rosslor equation )
