toolbox_nlmeans 用MATLAB实现非局部均值滤波算法(toolbox_nlmeans)

This code implements the search algorithms described in [1]. The code only contains the Dirichlet/Multinomial case, but the Gaussian case can be hacked in in about 5 minutes. [1] Fast search for Dirichlet process mixture models Conference on AI and Statistics (2007)

This is a goertzel filter in Simulink, it decodes DTMF tones and displays the detected numbers.

本书介绍了小波变换在地震资料处理中的应用，并介绍了MATLAB工具箱(This book introduces the application of wavelet transform in seismic data processing, and introduces the MATLAB toolbox )

In this file, the case of polymer casting is considered as an unsteady state heat transfer problem. The explicit scheme of finite difference approach is considered to solve the governing partial differential equation in one dimensional (radial) cylindrical coordinates.

fft离散傅立叶变化，广泛应用数字信号处理中。(Discrete Fourier fft change, the wider use of digital signal processing.)

这个身重要，基于matlab的三维时域有限差分程序（UPML各向异性的完美匹配吸收层），使学习时域有限差分方法的好资料。(The body important matlab-based three-dimensional finite difference time domain procedures (UPML anisotropic perfectly matched layer), enabling learners to FDTD good information.)

说明：  bp神经网络对字母的识别，在matlab里运行，并且附带程序和运行后的图像，(The bp neural network recognition of letters, running in the matlab, and the supplementary program and after the operation of the image,)

pagerank的matlab实现，已经调试通过，可以直接使用。(pagerank matlab implementation, debugging has been passed, can be used directly.)
