Matlab中虽然有很多解方程的函数，但对于一般线性方程，有无穷个解时，却不能算出一个特解和基础解系，这几个函数可以实现这个功能。(Matlab Although there are many solutions to the equation function, but for the general linear equations, Infinite Solutions months, they can not penetrate a special solution and infrastructure solutions, which have several functions to achieve this function.)
