说明：  一个实用简单的平面坐标转换小程序MAtlab(A simple plane coordinate conversion utility applet MAtlab)

matlab实现，绘制二维及三维HHT谱图(Matlab implementation, draw 2D and 3D HHT spectrum)

Consist of SPWM Generator. Three phase inverter with pulses.

层次分析法的Matlab界面，用于AHP的处理计算(The interface of AHP build in Matlab)

信号包络提取代码。可以方便地获取信号包络曲线。应用效果较好！(envelope matlab code)

很实用的一个OFDM仿真程序，OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图，将每个子信道上的数据，映射到星座图点的复数表示，转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )

正确率可以达到98％，匹配追踪和正交匹配追踪，基于分段非线性权重值的Pso算法。( Accuracy can reach 98 , Matching Pursuit and orthogonal matching pursuit, Based on piecewise nonlinear weight value Pso algorithm.)

这里面是关于微波技术的一些试验程序，和仿真模型，主要有微带线，带状线，功率分配器，支节匹配器(This is on microwave technology, which some experimental procedures, and simulation models, mainly microstrip, stripline, power divider, branch of the matcher)

matlab4.2 数值计算与编程 版本稍微有点老，还是有参考价值的(Numerical Methods and Programming matlab4.2 slightly older version, or a reference value)
