说明：  遗传算法，matlab实现。包含一整套源码(Genetic algorithm, matlab implementation)

The attached file is a tutorial on matlab that will provide the necesssary guidance to those programming in matlab.

在轴箭头绘制坐标空间是很困难的，因为Matlab的内置函数图工程箭头坐标空间。这个函数的轴到图坐标计算及放置在正确的位置注释箭头。它还提供了一个按钮式功能重新同步线和箭头如果调整轴或人物，或变更线的属性。(Plotting an arrow in axis coordinate space can be difficult, since Matlab s built-in arrow function works in figure coordinate space. This function does the axis-to-figure coordinate calculation and places an annotation arrow in the correct location. It also provides a button-down function to re-sync the line and arrow if you resize the axis or figure, or change the line properties.)

《Wireless Communications and Networking》（《无线通信和网络》）配套MATLAB源码。该书涵盖了第一、二、和三代蜂窝通信系统从物理层到网络层的关键特性。("Wireless Communications and Networking "(" wireless communications and networks ") supporting MATLAB source. The book covers the first, two and three generations of cellular communications system from the physical layer to the network layer of the key characteristics.)

针对主成分分析的很实用的程序，只需要把所掌握的数据带入，就可以获得一系列的数据，包括相关矩阵、载重、主成分贡献率等。(Principal component analysis and practical program, simply put into the master data, you can get a range of data, including the correlation matrix, load, principal component contribution rate.)

用场强仪采集数据后，可进行场强分布分析，并绘制出场强分布图。(Strength Meter data collection, field intensity distribution analysis, and draw the intensity distribution of the appearance.)
