一个有用的非线性微分方程的matlab程序集(A useful matlab package for nonlinear PDEs)

This toolbox was designed as a teaching aid, which matlab is particularly good for since source code is relatively legible and simple to modify. However, it is still reasonably fast if used with the supplied optimiser. However, if you really want to speed things up you should consider compiling the matrix composition routine for H into a mex function. Then again if you really want to speed things up you probably shouldn t be using matlab anyway... Get hold of a dedicated C program once you understand the algorithm.

用matlab仿真2PSK、4FSK的波形(Using matlab to simulate the waveform of 2 PSK, 4 FSK)

说明：  升余弦滚降信号及其功率谱。可以通过它实现通信系统中常用的升余弦滚降系统。用处极大哦~(Raised cosine roll-off signal and its power spectrum. Can achieve through its communication systems commonly used raised cosine roll-off system. Oh ~ great usefulness)

说明：  通信传输过程中使用TCM 维特比编译码的源程序 包括编码和解码两个子程序，可以绘出误码率曲线(Communication transmission TCM Viterbi decoding using the source code, including encoding and decoding of two subroutines, you can draw the curve of bit error rate)

当时做项目时候用到的PIDZ专家控制，效果很好(When used at the time to do the project PIDZ expert control, with good results)

基于MATLAB和usb外置声卡的信号回检，检测信号频率，幅值，功率等。(Based on MATLAB and usb external sound card signal back to check, test signal frequency, amplitude, power, etc..)

说明：  MATLAB有限元分析与应用，适用于matlab编程研究人员(Finite element analysis and application of MATLAB, matlab Programming for Researchers)
