代码说明：

  NMFs算法（带稀疏度约束的非负稀疏矩阵分解）用于实现基于人脸局部特征的人脸识别，通过近似的矩阵分解进行空间降维。(NMFS algorithm (sparse with degree-constrained non-negative sparse matrix factorization) for the realization of human faces based on local features of face recognition, through approximate matrix factorization space dimensionality reduction.)
