QPSK调制与解调，低通滤波器采用了时域和频域两种实现方式，截止频率fc = 200hz,采样频率fs= 1000hz,欢迎下载参考！(QPSK modulation and demodulation, using a low-pass filter with a time domain and frequency domain implemented way, the cutoff frequency fc = 200hz, the sampling frequency fs = 1000hz.Welcome to download !)

该燃机模型包括压气机、燃烧室、透平、转子、控制器等模型部件，实现了变负荷过程中，燃机转速调整的目标(The model includes gas turbine compressor, combustor, turbine rotor, controllers and other model components, to achieve a variable load process, the gas turbine speed adjusted target)

关于边缘检测各种算法的比较研究，包括roberts，sobel，prewitt，LOG，canny等五种(Edge detection algorithms on the comparative studies, including roberts, sobel, prewitt, LOG, canny and other five)

用matlab实现三级小波分解，希望对初学者有所帮助(Using matlab to achieve three wavelet decomposition, want to be helpful for beginners)

The basic steps of the edge-based text extraction algorithm are given below 1. Create a Gaussian pyramid by convolving the input image with a Gaussian kernel and successively down-sample each direction by half. (Levels: 4) 2. Create directional kernels to detect edges at 0, 45, 90 and 135 orientations. 3. Convolve each image in the Gaussian pyramid with each orientation filter. 4. Combine the results of step 3 to create the Feature Map. 5. Dilate the resultant image using a sufficiently large structuring element (7x7 [1]) to cluster candidate text regions together. 6. Create final output image with text in white pixels against a plain black background.

说明：  这些程序是MIT学生学习Matlab时的教学程序，能面还有个pdf文档附有每个程序所实现的功能(This is the teaching codes at MIT for learning Matlab. hope it is helpful for you.)

浙江大学数学建模比赛2013B题Matlab源码，主要使用遗传算法和模拟退火解决自行车调度问题，此处为有时间窗的VRP问题，注释详尽，方便改进维护(Zhejiang University Mathematical Contest in Modeling 2013B title Matlab source code, detailed notes, easy to improve maintenance)

对井下放炮，地面接收地震资料进行偏移。长测线同样适用。(Underground blasting, ground receiving seismic data offset. Long lines are equally applicable.)

基于MATLAB的车牌识别系统，附有源程序代码和一幅图片例子(car board localization)

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.
