离散余弦变换的压缩程序MATLAB实现的，大家可以试一试！(Discrete Cosine Transform compression program MATLAB to achieve, we can try!)

说明：  对测试图像分块、DCT和量化，将量化后的系数写成矩阵形式。(The test image block, DCT and quantization, the quantized coefficients written in matrix form.)

ffmpeg 是一个开源、功能强大的多媒体处理软件，可以实现对音频流、视频流的录制和转换。(ffmpeg is an open source, powerful multimedia processing software, which enables audio streaming, video streaming recording and conversion.)

常用图像压缩编码码matlab实现。包括：DM编码、变换编码（FFT和DCT）、算术编码、行程编码、Huffman编码、线性预测编码和一个近似的JPEG编码过程。非常适合入门用户实践。(Commonly used image compression coding matlab code to achieve. Including: DM coding, transform coding (FFT and DCT), arithmetic coding, Run-Length Coding, Huffman coding, linear predictive coding and a process similar to JPEG encoding. Very suitable for the practice of entry-users.)

输入两个正整数m和n，求其最大公约数和最小公倍数(Enter two positive integers m and n, can seek the common denominator and least common multiple)

说明：  huffman编码，根据输入进行权重计算并编码，还实现了解码。(Huffman coding, according to the input weight calculation and coding, but also achieve decoding.)

说明：  此压缩文件里面包含面板数据熵值法的stata代码，每一步都有详细的解释，并且附有样本和数据，方便学者理解和掌握。(This compressed file contains the stat a code of panel data entropy method, each step has a detailed explanation, and is attached with samples and data, which is convenient for scholars to understand and master.)
