this is a code to use for speech recognition, it has another code instead of this code, call me for more detail

Matlab数值积分与微分的讲稿，详细介绍各个指令的用法及例子(Matlab numerical integration and differentiation of the script, detailed usage instructions and examples of various)

最小费用最大流问题是经济学和管理学中的一类典型问题。在一个网络中每段路径都有“容量”和“费用”两个限制的条件下，此类问题的研究试图寻找出：流量从A到B，如何选择路径、分配经过路径的流量，可以达到所用的费用最小的要求。(Minimum cost maximum flow problem is economics and management in a class of typical problems. Each path in a network has the " capacity" and " costs" two limiting conditions, such problems of trying to find out: Flow from A to B, how to choose the path, the path of the flow through the distribution can be achieved The use of the minimum cost requirements.)
