问题描述:用Mathematica写程序,如果调用Solve[ ]出现某种异常,则中断计算,返回错误信息。
代码实现:
sol = Check[Solve[EQ, vars], Print["The number of variables is greater than the number of equations."]; Abort[],Solve::svars]; If[Length[sol]==0, Print["There is no solution."]; Abort[] ];说明:如果Solve求解中出现 Solve::svars 的错误,则打印警告,用Abort终止计算;否则检查是否是无解。
