网上收集的几个半角字符转全角字符的函数。-Online collection of half-angle of several characters in turn a function of full-width characters.

LTE 3GPP channel modeling using matlab.   Generates the correlated tap coefficients of the MIMO tapped delay line % model to be used during one iteration of the main loop. The function % performs a double interpolation, first in the fading vector domain, % to collect the fading samples corresponding to the (sub)chip-spaced time % samples, then in the tap domain, to match the delays of the PDP to % the sample instants of the simulation. This second interpolation complies % with the description in TR 25.869

应用背景该例程实现28335与芯片AD5621的SPI通信，有很多新手不会根据所需芯片来配置f28335 SPI的寄存器，这里给了一个实例，很值得学习，我也是查看了很多资料才配置成功的 （代码也有很多注释），并且是我调试通过的！！关键技术SPI是串行外设接口（Serial Peripheral Interface）的缩写。SPI，是一种高速的，全双工，同步的通信总线，并且在芯片的管脚上只占用四根线，节约了芯片的管脚，同时为PCB的布局上节省空间，提供方便，正是出于这种简单易用的特性，如今越来越多的芯片集成了这种通信协议，比如AT91RM9200。
