运用非负矩阵分解算法分解原始数据矩阵，得到基矩阵和系数矩阵，并用于信号分离。(The non-negative matrix decomposition algorithm is used to decompose the original data matrix, and the base matrix and coefficient matrix are obtained.)

已有的文本过滤受限，所以对现有的文本过滤软件进行了算法改进，对现有的问题进行分析，故而有着实用价值，但是文本过滤仍然有着不能弥补对图形图象的无效，所以有必要对图象视频等进行过滤(Already limited text filtering, so the existing text filtering software algorithms to improve on the existing analysis of the problem the club would have practical value, but still have a text filter should not make up for the graphic image is invalid, there is necessary to filter the video image)

此书包含了MATLAB的所有命令，对学习MATLAB的学者很有帮助，也可作为一本工具书。(This book contains all the MATLAB commands, useful for learning MATLAB scholars, but also can be used as a tool.)
