matlab简明教程，有大量实例，供大家参考学习！(matlab simple tutorial, a large number of instances, for your reference to learn!)

一系列展示图像压缩技术的源代码。包括有：使用块截断编码的图像压缩(Block Truncation)、基于高斯金字塔变换的图像压缩(Gaussian Pyramids)、基于离散余弦变换对图像压缩(Discrete Cosine Transform)、基于奇异值分解(SVD)的图像压缩(Singular Value Decomposition)。给出的代码还可以用于2D图像噪声消除。(Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.)

this is matlab code about 802.11b PHY.DBPSK

由于最近做一个项目需要对MATLAB电路图做测试，且需要满足MCDC且覆盖每个门，由于 手工生成非常麻烦而且也容易出错，所以做了个工具来自动生成测试用例(With the recent need to do a project on the MATLAB test circuit, and the need to meet and MCDC coverage of each door, hand-generated as a result of a very troublesome and error-prone, so do a tool to automatically generate test cases)
