// 函数原型
void CONV(complex<double> * TD1, complex<double> * TD2, complex<double> * TDout, int M, int N);
void CORR(complex<double> * TD1, complex<double> * TD2, complex<double> * TDout, int M, int N);
void CONV2(complex<double> * TD1, complex<double> * TD2, complex<double> * TDout, int M1, int N1, int M2, int N2);
void CORR2(complex<double> * TD1, complex<double> * TD2, complex<double> * TDout, int M1, int N1, int M2, int N2);
