决策树的Matlab实现，实现了分类问题和回归问题，有很好的调试结果(Matlab implementation of decision trees)

这个文件实现了Matlab/Simulink中的三维查找表，对要用到查表的人有帮助，里面用到Reshape函数(This file implements the Matlab/Simulink in a three-dimensional look-up table for use to help people look-up table, which used Reshape function)

试用时域最小平方误差准则（最小平方逆设计）设计一个具有四项系数的IIR DF的系统函数，使其在y(n)=[3,2,1]输入激励下，输出v(n)逼近d(n)=[2,0.2,0.05]。令v(-1)=v(-2)=0。求出v(n)的前8个样值与d(n)进行比较。用matlab实现了此要求。(trial at the least square error domain guidelines (minimum inverse square design) design with a four DF IIR coefficient of the system function, so in y (n) = [3,2,1] incentive to import, export v (n) approximation d (n) = [2,0.2,0.05]. So v (1) = v (2) = 0. Get v (n) of eight samples value d (n) comparisons. Using Matlab realization of this request.)

：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.)
