这是信号分析课程中的作业，本程序产生QPSK信号(This is a signal analysis course in the operation, the procedures QPSK signal)

OFDM simulation for transmission and reciever

说明：  对MFO算法飞蛾位置更新方法进行改进，加快其收敛速度(The moths position updating method of MFO algorithm is improved to accelerate its convergence speed)

IMPMET Standard impedance matrix (metal surface) Returns the complex impedance matrix [EdgesTotal x EdgesTotal] Uses 9 integration points for every triangle (barycentric subdivision) The impedance matrix is calculated as a sum of the contributions due to separate triangles (similar to the "face-pair" method).

计算Fisher的函数，根据Fisher可以计算出克罗美下界(Fisher s exact test is a statistical test used to determine if there are nonrandom associations between two categorical variables[1]. The job of Fisher s exact test with 2 x 2 or 2x 3 contingency table is already easily done by others. However, the one with n x m contingency table hasn t found , or with bad computation. This function efficiently deals with Fisher s exact test with n x m contingency table. As for the function :)
