说明：  matlab图形图像处理方面的书籍，pdf电子书(graphic image processing matlab books, pdf e-book)

根据小波研究专家编写的“小波处理的小波导引”，当中所涉及到的所有程序都在这里，学习小波和信号处理不得不看的程序(All programs written based on wavelet research experts' guide wavelet wavelet processing " , which involved all here to learn Wavelet and signal processing have to look at the program)

研一上学期，学校开了数值分析这门课，而且要求用matlab进行上机试验，经过一段时间的学习，对matlab有了最初步的了解，结合所学课程，废了好大的劲才编了几个小程序，希望对后来学习的人有点帮助。(Kenichi last semester, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, after a period of learning, of matlab with the most basic understanding, combined with the course, the repeal of several large series劲才a few small programs, and they hope to learn a little bit later to help.)

电力系统故障计算，可以计算单相短路，单相接地短路，三相短路，两相短路接地，两相短路(power system fault, can calculate the single-phase short circuit, short-circuit to the single-phase and three-phase short-circuit, two-phase short-circuit grounding, two phase short circuit)

可实现对灰度图片的小波变换，达到图像增强以及图像去噪功能(Grayscale images can be dealed with the wavelet transform, so to tealize image enhancement and image denoising function)

带阻滤波器，包括程序和一个实例，程序每句都有注释，这样更加易懂(Bandstop filter comprising an instance of the program, and the program has a comment sentence, so more understandable)

该程序为标准粒子群算法源程序，可以在此基础上改变参数，对程序进行优化(The program is the standard particle swarm algorithm source code, you can change the parameters on this basis, the program optimization)

说明：  应用BP神经网络对两个函数进行非线性逼近，并给出MATLAB源程序，还对结果进行了分析。(Application of BP neural network of the two non-linear function approximation, and gives MATLAB source code, but also on the results are analyzed.)

搭建pll电路，主要包括鉴相器，低通滤波器，压控振荡器，包括个部分的输出信号(Pll circuit structures, including phase detector, low pass filter, VCO, including a part of the output signal)
