第11章 解线性方程组的直接法.zip。是从书中光盘里直接拷贝的代码，放在这里，与大家共享，共同交流，希望对大家有帮助。(Chapter 11 the direct method of solution of linear equations)

根据IEEE标准算例给出的9节点网络图，利用MATLAB软件编程计算其节点导纳矩阵（含有解释）。当然，依据程序稍作修改可以求IEEE算例中的任意节点导纳矩阵。(Example is given according to the IEEE standard 9-node network diagram, using MATLAB software program to calculate the nodal admittance matrix (with explanation). Of course, some slight modifications according to the program can find examples of any IEEE nodal admittance matrix.)

有小波分析的盲信号处理，包含优化类的几个简单示例程序，相控阵天线的方向图（切比雪夫加权）。( There Wavelet Analysis Blind Signal Processing, Optimization class contains several simple sample programs, Phased array antenna pattern (Chebyshev weights).)

一个用MATLAB开发的GUI程序,程序本身是用来进行图像的灰度变换,但是是学习GUI入门编程的好代码,初学者不妨一读(Using MATLAB development of a GUI program, the program itself is used for images of gray-scale transformation, but to learn GUI programming a good entry-code, one may wish to read for beginners)

说明：  TURBO译码性能AWGN信道测试（菜单式） 达到误帧限即可停止当前SNR点的测试，节省计算量(TURBO AWGN channel decoding performance test (menu type) to stop the current error frame is limited to the test SNR point, saving computation)

利用matlab/simulink搭建了水轮机调速系统模型，考虑了频率死区和速率限制(model the hydraulic turbine governing system by matlab/simulink, considering the dead band and ramp limit )

demodulates the FM modulated signal Y at the carrier frequency Fc (Hz). Y and Fc have sample frequency Fs (Hz). FREQDEV is the frequency deviation (Hz) of the modulated signal.
