学习matlab GUI编程非常好的参考资料，王继盛(very good reference book for matlab gui.)

数学建模：长江水质评测,程序包含了预测模型(Mathematical modeling: the Yangtze River Water Quality Evaluation)

图像压缩预测编码.采用了差分脉冲预测编码的方法。(Image compression predictive encoding using a differential pulse predictive coding method.)

地球物理一维正演，包括瞬变电磁，CSAMT，电测深(Geophysical one-dimensional forward, including transient electromagnetic, CSAMT, electrical sounding)

随机产生二进制序列，进行128QAM调制，画出星座图，通过加性高斯白噪声的信道，再画星座图，并计算误比特率。(128QAM modulate with MATLAB)

说明：  这是matlab的根轨迹程序代码，很好很好的代码(This is the root locus matlab code, very good very good code)

：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.)

<<工程与科学数值方法的matlab实现>>此书中的源代码(the source codes for the book <<applied numerical methods with MATLAB for engineers and scienists>>)

说明：  基于matlab。利用FFT计算信号的频谱并与信号的真实频谱的抽样比较。 脚本文件T2F.m定义了函数T2F，计算信号的傅立叶变换。(Based on matlab. Calculated using FFT frequency spectrum and the true spectrum of the signal sample comparison. Script file defines a function T2F.m T2F, calculate the Fourier transform of the signal.)
