如何matlab求解多元方程
x,y,z,u]=solve('48.18577=x/[1+(6280000*x*z)^2]+y/[1+(6280000*y*u)^2]','655.3747=x*{6280000*x*z/[1+(6280000*x*z)^2]}+y*{6280000*y*u/[1+(6280000*y*u)^2]}','49.78774=x/[1+(5709085*x*z)^2]+y/[1+(5709085*y*u)^2]','724.7968=x*{5709085*x*z/[1+(5709085*x*z)^2]}+y*{5709085*y*u/[1+(5709085*y*u)^2]}')
每次运行总是出现如下错误,
Warning:Warning,solutionsmayhavebeenlost
Warning:Explicitsolutioncouldnotbefound.

方程没问题的但不知为什么就是不出结果
