作业帮matlab编程画图.等了好久了!>> syms xx z k D t m q T x;p=(x.^(1-m))*k*D*(t^m)*exp(q*(1/293-1/T))./(1.78*(1-m))-(0.5*z/xx)^2;pp=subs(p,{xx,z,k,D,t,m,q,T},{.2,0.06,7,3*10^-4,0.07,0.4,6100,293});solve(pp)这是我计算程序,我想画出这样

>> syms xx z k D t m q T x;
p=(x.^(1-m))*k*D*(t^m)*exp(q*(1/293-1/T))./(1.78*(1-m))-(0.5*z/xx)^2;
pp=subs(p,{xx,z,k,D,t,m,q,T},{.2,0.06,7,3*10^-4,0.07,0.4,6100,293});
solve(pp)
这是我计算程序,我想画出这样一种图,比如：想画x-xx的图,但是要取不同的k值,其他参数都是定值.怎么写程序呀?

这样就可以运行了：
syms xx z k D t m q T x;
p=(x.^(1-m))*k*D*(t^m)*exp(q*(1/293-1/T))./(1.78*(1-m))-(0.5*z/xx)^2;
pp=subs(p,{xx,z,k,D,t,m,q,T},{.2,0.06,7,3*10^-4,0.07,0.4,6100,293});
X=double(solve(strcat(char(pp),'=0'))) %求解pp中的x的值
ezplot(char(pp)) %画pp的图,当然你也可以用plot,具体实现方法,请自己看一下帮助.
结果：
X =
342.1045
希望能帮到你!
