水和水蒸气性质源代码，可以通过6个参数中的2个差出另外的4个，很实用。(m_watertoolbox sours code)

异步电动机转差频率控制系统仿真，在matlab7.0下运行没任何问题，转速、磁链等参数都有显示，适合想要学习电机控制方针和矢量控制的。G1=35，G2=0.15，G3=0.0076，G4=2，G5=G6=9.55(Asynchronous motor slip frequency control system simulation, under the matlab7.0 running without any problems,, according to the parameters such as speed, flux has suited to want to learn motor control principle and vector control.)

基于SIRP方法的相干相关K分布雷达杂波的建模与仿真程序，包含三个文件。主文件为K_distribution.m，两个函数文件nonline_eq_sirp.m，fseries.m。(K-distribution radar clutter simulation code based on SIRP method,including three files. The main file is K_distribution.m, the two function files are nonline_eq_sirp.m，fseries.m respectively.)

Seismic SEG-2 file format reader to matlab

文件中包含一个地形数据，一个将此数据用matlab进行三维显示的程序。自己写的，可用于航迹规划中的地形测试。(The file contains a terrain data, three-dimensional display this data using matlab program. Write their own terrain test can be used for route planning.)

说明：  Multirate滤波器设计。模拟带通信号频率范围1KHz—1.1KHz，设计一个采样频率8KHz数字频谱分析系统，要求频率分辨率0.1Hz。(Multirate filter design. Analog bandpass signal frequency range 1KHz-1.1KHz, design a sampling frequency of 8KHz digital spectrum analysis system, required frequency resolution of 0.1Hz.)

绘制二维非线性系统的相图，MATLAB程序，自已编写，多多交流！(Phase diagram, drawing two-dimensional nonlinear system MATLAB program, written, more exchanges!)

This code simulates QPSK modulation on base band. This code has been written on Matlab and it will be very useful I think! :)

说明：  输入信号为谐波信号，用brug算法运算线性模型系数。(Input signal for the harmonic signal, using brug coefficient linear model algorithm.)
