计算一个非负整数矩阵的铪质。注：复制铪质。C的方法。
代码说明：
Computes the hafnian of a nonnegative integer matrix. Notes: Copy hafnian.c to main.c, in the same directory as Rothberg s code (see above). You can download the .tar directory with the code weighted-match.tar here. Then "make" the codes (this codes are in C, not C++). The program is then run by the command "wmatch". -Computes the hafnian of a nonnegative inte ger matrix. Notes : Copy hafnian.c to main.c, in the same directory as Rothberg"s code (see abo ve).
