说明：  本代码用于matlab中数字信号得快速傅里叶变换及频谱分析(This code is used in matlab digital signal FFT and spectrum analysis)

matlab编写的文件名批量修改程序，比较实用，可是试试看(matlab batch file name written in the amendment procedure, more practical, but give it a try)

isar成像之前做的，用于回波数据的处理，比较有用的(isar imaging done before, for the echo data processing, the more useful)

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.

MATLABLE学习书籍电子版，从简单到困难，提高给大家参考(MATLABLE learning books electronic version, from simple to difficult, to improve to everyone reference)

图像处理：用MATLAB实现的维纳滤波、约束最小二乘，Lucy-Richardson迭代和盲去卷积算法，并带有GUI。(ImageDeblurring:Implement deconvwnr, deconvreg, deconvlucy, deconvblind with MATLAB, GUI appended.)

1. 识别同一个乐器弹奏出的不同音符（基波分析） 2. 识别弹奏出同一个音符的不同乐器（谐波分析）(1. identify the different notes played by the same instrument (fundamental analysis). 2. identify different musical instruments playing the same note (harmonic analysis).)

遗传算法优化后计算潮流的一个改进程序，给大家看看(Genetic algorithm optimization of a trend of improvement after the calculation procedure for everyone to see)
