matlab Unbalanced or unexpected parenthesis or bracket.本人初学者,

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？
