这是用C++做矩阵求逆和矩阵相乘，可以解简的线性方程。已验证，互相交流~(This is done using C++ matrix inversion and matrix multiplication, linear equations can be solved。)

说明：  在进行激光熔覆或者焊接时可用到的移动热源命令流(Command flow of moving heat source available during laser cladding or welding)

对简单开式网前推回代法计算潮流方便，已通过编译，有运行结果(back forward power flow)

基于交替方向乘子法的非负矩阵分解算法，主要用于盲分离(Alternating direction multiplier method based on non-negative matrix factorization algorithm, mainly used for blind source separation)

求解声学问题的边界元源程序，可以为使用边界元法求解位势问题和弹性力学问题提供启发(problem solving acoustic BEM source, for the use of the boundary element method and the potential problems of elasticity to provide inspiration)

有限元计算控制加载中弧长法（arc-length）的matlab源程序(Loading FEM arc length control method (arc-length) matlab source)

非负矩阵分解的最经典算法，1999发表在自然科学杂志上的那一篇文章的代码(classic Nonnegative matrix factorization)

基于多相结构的信道化接收机，模拟数据分析处理的过程，时间序列数据分析中的梅林变换工具。( Channelized receiver based on multi-phase structure, Analog data analysis processing, Time series data analysis Mellin transform tool.)

说明：  fractal compression using wavelet

根据输入的长宽，计算Rectangle面积周长等功能，并画出在txt文件中(Rectangle Create a class Rectangle with attributes length and width, each of which defaults to 1 a. Provide member functions that calculate the perimeter and the area of the rectangle. b. Also provide set and get functions for the length and width attributes. The set functions should verify that length and width are each integer numbers larger than 0 and less than 20. c. Write draw function to display the Rectangle: in Assignment1. ) d. Write a driver program to test class Rectangle.)
