再问： Price1=zeros(1,20); Price2=zeros(1,20); power1=zeros(1,20); power2=zeros(1,20); power1(1)=subs(Pr1o,p1,p11);%节点1在各节点都报价c(此时为了后面的整体行，用p11代替c1)时的最佳功率power2(1)=subs(Pr2o,p2,p22); 报错是The following error occurred converting from sym to double If the input expression contains a symbolic variable, usethe VPA function instead. 可以帮忙看下吗？

matlab 出错Error: Unbalanced or unexpected parenthesis or brac
matlab中输入下面语句显示Error:Unbalanced or unexpected parenthesis or
关于matlab的Error:Unbalanced or misused parentheses or brackets
MATLAB错误：Unbalanced or misused parentheses or brackets,
Pls translate the words or sentence parenthesis into Chinese
III.Rewrite each sentence with the word or phrase in bracket
Unexpected MATLAB operator.
matlab提示Error:Incomplete or misformed expression or statemen
matlab提示：Incomplete or misformed expression or statement.
matlab中Error:Missing variable or function.
本人初学者编了个MATLAB程序一直运行不成,求
Error: Unexpected MATLAB operator. 在线等,谢谢
