I want to plot different graphs on the same axis for a fucntion S=f(z) at differente initial conditions Ti1 Ti2 and Ti3.
Init=[Fi1 Fi2 Fi3 Fi4 Fi5 Ti1
Fi1 Fi2 Fi3 Fi4 Fi5 Ti2
Fi1 Fi2 Fi3 Fi4 Fi5 Ti3];
for i=1:2
x0=Init(i,:);
zspan=[0 L];
[z,x]=ode45(@mbrf,zspan,x0,[],Pt,rhoc,epsilon,Re,Ri,Perm4,Perm5,dHr1,dHr2,Tv,R,ms,dp,Po,Pa,MW1,MW2,MW3,MW4,MW5);
plot(z,S,'r-','MarkerSize', 1,'LineWidth', 1), xlabel('z(m)'), ylabel('S')
hold on
end

Hi Paulino,
The error you are encountering is because of the difference in size of the “z” and “S” vectors in your code. You can check the size of a vector using the “size” function. Please ensure that both “z” and “S” are the same size.
Refer to the following documentation link for the “size” function - https://www.mathworks.com/help/matlab/ref/double.size.html
I hope this resolves your query. Happy coding!
