Simulation of digital baseband modulation,it is very good for the users to deepen their understanding

Fitcircle matlab code

简单实用的手写板，可以触摸笔写入汉字，画出任意图形(Simple and practical tablet, you can touch pen to write Chinese characters, to draw any graphics)

这是学习matlab的非常实用的程序Matport是NTPort Library的MatLab接口模块。借助Matport，你可以在Matlab中直接访问PC 的I/O端口。(Before use Matport, your must install the latest version of NTPort Library. And copy all files of Matport into MatlabWork directory. Start Matlab, and now you can use matport command to call NTPort Library functions. The basic syntax of Matport is as follows, matport( NTPort Library funtion , parameters...) For example, if you want to call Inport function to read a port, simply use myvalue = matport( Inport , 97) Port address 97 is as a decimal.)
