matlab用plot画图出现错误 Error using ==> plot Conversion to double from sym is not possible.
程序如下：
[ph2,po2]=dsolve('0.005/8.314/T*Dph2=nh2*uf-6.435*10^(-7)*(ph2-3.03*10^5)-0.5*40*i/96485','0.01/8.314/T*Dpo2=nh2*uf/rho-6.435*10^(-7)*(po2-3*10^5)-0.2*40*i/96485','ph2(0)=0','po2(0)=0');
i=10,nh2=0.1,uf=0.7,T=60;
t=0:0.01:150
运行时出现错误,

ph2,po2为复数解,所以plot不能完成画图
