When i saved my code ? I am getting this error "Undefined function 'X0' for input arguments of type 'double'". Why is that?

Tb0 =100;
Tvc =110;
% initialisation du débit de la vapeur de chauffage (Mvc) en [kg/s] 
x0(5*n+1)=((Uh*Ah)/Ls)*((Tb0-x0(4*n))/log((Tvc-x0(4*n))/(Tvc-Tb0)));
help please!!

This clearly isn't all your code else it won't run for very obvious reasons. Is x0 defined somewhere as a function or is it an array?

You have to define x0, Uh, Ah,Ls, n and then run the code. You have no initialized many parameters.

i define all this Uh Ah Ls n the xo is to initialize a parameter value

x0 is not a fixed data

There is no x0, Uh, Ah,Ls, n defined in the code...
