ldpc码的matlab仿真程序，信息序列较小，但仿真效果好。(LDPC codes matlab simulation program, the information sequence of smaller, but better simulation effect.)

说明：  完整的QPSK的调制与解调，已调试通过，认真学习一下(QPSK modulation and demodulation)

SIGNAL PROCESSING IN MATLAB

This Algorithm comutes demagnetizig tensor from Newell Paper[1] between two rectangular shape elements.Main function is and there is equivallent function written in c-language, you can use it to compile mex file.This script can be used in field of micromagnetics and finite difference magnetic simulation software. 1.
