自己编的一个chase算法的小程序，只进行了一次迭代运算，关于多次迭代计算需进一步研究(developed an algorithm for small chase procedures, only a iteration, on the number of iterative calculations required further study)

人工合成地震记录人工合成地震记录人工合成地震记录人工合成地震记录(seismic data seismic data seismic data)

这段代码使用matlab实现匈牙利算法的匹配问题(This algorithm allows you to find the minimum weight matching of a bipartite graph. The graph can be of arbitrary size and connectedness. The edge weights are captured by a MxN weight matrix where an infinite(Inf) weight designates that that pair of vertices given by that position are not connected.)
