This exchange file creates a clickable image map for a figure with links to multiple data sources

关于matlab7.0三维绘图的，有很强的指导性和实践性。(Three-dimensional drawing on matlab7.0, has a strong and practical guidance.)

MATLAB中，一幅图像可能包含一个数据矩阵，也可能包含一个颜色映射表矩阵。 (MATLAB, an image may contain a data matrix. may also include a matrix color mapping table.)

This mfile simulates adaptive spectrum sensing.

书号的识别程序，带有相应的图解。可以作为识别的参考程序。(ISBN identification procedures, with the corresponding illustrations. Identification procedure can be used as a reference.)

DS-CDMA仿真源程序，内附详细说明文档，适合初学者(DS-CDMA simulation source code, containing detailed documentation, suitable for beginners)

以循序漸進的方式介紹 MATLab 這種科學程式語言，並透過易懂的範例讓讀者更能快速了解。(MATLab gradual way to introduce this scientific programming language, and through the example of readers better understand quickly understand.)

这是一个利用MATLAB的GUI编的长直导线周围电磁场的可视化程序。(This GUI provides a visualization of the electromagnetic field induced by a current flowing in a straight wire. The tool also shows the current induced by a rectangular coil that is placed inside the electromagnetic field. The current is calculated using Ampere s Law and the Biot-Savart Law. This demo was created for educational demonstrations. The user can modify the size and position of the coil, as well as the resistance. The current waveform and magnitude can also be specified.)

说明：  该程序给出了OFDM信号以及频谱分析，也插入了保护间隔(the procedure given OFDM signal and spectrum analysis, insert a protective partition)
