非负矩阵分解的人脸识别NMF 可正常运行 算法源码(Non-negative matrix factorization NMF for face recognition algorithms can be the normal operation of source)

这段代码主要用于工程中的结构有限元设计，依次从代码中很容易求解出结构所划分的节点数，单元数以及荷载等。(This code is mainly used for finite element in structural engineering design, are easily solved by the number of nodes in the structure of the number of units, and load.)

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)
