matlab程序，二维矩量法，无限长圆柱散射(matlab progress)

This function Simulates the swing equation of a one-machine system and returns the critical clearing time for stability.

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations
