This question is not a clear cut question. The general answer is YES, MODEL, NLIN and many other SAS procedures can be used to solve system equations. But, keep in mind that SAS is a numerical software, not symbolic, it will give you the numerical solution, not the analytical. Besides, all the computations are on the domain of real number, it depends upon how do you formulate your equations.作者: shiyiming 时间: 2004-2-28 13:00 标题: Thank you! Many thanks to you. I will try it with sas, I have solved it by using Matlab.
My equation isn't linear.作者: shiyiming 时间: 2004-2-28 23:20
SAS的IML在求解方程方面应用较为方便，值得一试。
