说明：  用matlab仿真的信号的fft变换的时域,频域图形(simulation using Matlab Signal fft transform in time domain, frequency domain graph)

MIMO-OFDM系统的仿真，MIMO-OFDM系统的每个模块都有，都能成功仿真(MIMO-OFDM system simulation, MIMO-OFDM system, each module has, can successfully simulate)

基于MATLAB的图像数字水印技术源代码，使用的是英文的解说，看懂应该没有什么问题,dct域和DTF域的(MATLAB-based image watermarking technology source code, using the English definition should read no problem, dct domain and domain DTF)

avi2apic AVI提取帧 忽略对视频压缩方法(avi2apic AVI to a picture)

Introduce how to use matlab to solve many variety problems.

该方法 基于快速傅里叶变换，求解方形区域的poission方程 比差分 有限元快。

This is a simple position location algorithm using Least Square Estimation algorithm. Timing information is time of flight (TOA) of signal between Tx and Rx. This code generally describes the Positioning method, Also it plots final coordinate of node in 2D. All other information was inlcuded as comments in source code.

此源码用于对一些非线性的方程组进行求解，时间复杂度比较小，效率比较高(This source is used for some non-linear equations is solved, the time complexity is relatively small, more efficient )

代码给出了数字图像处理图像复原运算方法中的自适应滤波、正则化滤波、盲去卷积滤波等滤波方法的实现过程，经matlab调试运行成功，效果明显(Code gives a computing method of digital image processing image restoration, adaptive filtering, regularization filter, blind go convolution filtering and other filtering methods to achieve process matlab debugging run successfully, the effect is obvious)

地震数据剖面显示程序，能将matlab数据按常规剖面显示（正值部分涂黑，负值部分不变）。(Seismic data profiles show program, matlab data can be displayed conventional profile (a time when parts blacked out, the negative part of the same).)
