一个matlab程序,实现小波分解和重构的程序(A matlab program to realize the procedure of wavelet decomposition and reconstruction)

：SPWM调制技术是通过改变输出方波的占空比来改变等效的输出电压，其调制波为正弦波，脉冲宽度间占空 比按正弦规率排列， 这样输出波形经过适当的滤波可以做到正弦波输出。它广泛的用于支流交流逆变器。本次实 验使用Matlab/Simulink对SPWM技术进行仿真并分析数据。(: SPWM modulation by changing the duty cycle square wave output to change the equivalent output voltage, the modulated sine wave, pulse width, duty cycle between the rate at sine arranged so that the filter output waveform can be done properly to the sine wave output. It is widely used in branch AC inverter. The experiment uses Matlab/Simulink simulation of the SPWM technique and analyze data.)

應用和弦搜索演算法(HS)求解目標-武器指派問題(WTA problem)，該程式碼輔皆有註譯以幫助理解，適合初學者使用。(Use the HS algorithm to solve the problem of weapons assignment (WTA problem), the code are accompanied by annotations are translated to help understand, suitable for beginners to use.)

基本的调制解调程序集matlab在simulink下的仿真(Modem basic assembly of matlab simulation in simulink)

卡尔曼滤波器介绍,北卡莱罗纳大学的,已经翻译成中文版了(Kalman filter, the University of North Kalailuona, has been translated into the Chinese version)

说明：  matlab数学建模 （李昕）清华大学出版社 全书附带源码(The Chinese book of "Matlab Mathematics Modelling" from Tsinghua University Press original code.)

模糊自适应控制，采用simulink 建模仿真，可以直观的看到系统输入和输出的关系，本人已调试成功。(fuzzy control)

经验似然计算 在非参数统计推断中可以构造似然比， 很有用。(empirical likelihood)
