矩阵

代码说明：

  这是几个关于矩阵计算的matlab程序,它有一套程序扩展系统和一组称之为工具箱（toolbox）的特殊应用子程序。工具箱是MATLAB函数的子程序库，每一个工具箱都是为某一类学科专业和应用而定制的，主要包括信号处理、控制系统、神经网络、模糊逻辑、小波分析和系统仿真等方面的应用。(Here are some matlab programs for matrix calculations, which have a program extension system and a set of special application subroutines called the toolbox. The toolbox is a function of MATLAB subroutine library, each toolbox is for a class of professional disciplines and application customization, including the application of signal processing, control system, neural network, fuzzy logic, wavelet analysis and system simulation etc..)
