RSA算法加密和解密。作为理解RSA算法非常好的程序，但不能用于工程中，因为本程序只支持很小的规模。-RSA encryption and decryption. RSA understood as a very good procedures, but not for the project, because the procedure will only support a very small scale.

复杂网络BA无标度网络的C++代码，可求其度分布。-Complex network of BA scale-free network of C++ code, rectifiable the degree distribution.

利用matlab构建BA无标度网络，进而研究复杂网络模型-Using matlab to build BA scale-free network, and then study the complex network model
