Good morning people,

I have a big algorithm and I would like to use different data without having to repeat the algorithm (for and if loops) many times. Any idea how?

I am pasting some part of my code as an example:

 if j==1
       Tin(j)=20;
       Con(j) = H1(j)+Qel(j)*u(j);
       NL_(j) = Con(j) - PV1(j);
       
        Terr(j)=Ts(j)-Tin(j);
        u(j)=0;
        SOC(j)=0.5;
        if Terr(j)>=1
        u(j)=1;
        end
 end
 
 

I would like to change H1 for H2, H3,... Hn, as well as PV1, PV2,... PVn

hi

your code should be declared as a function and then you pass the arguments, and do loops for differents inputs

see matalb doc about how to create functions

The source of your problem is that you chose to put data (i.e. the counter) in the variable name.

You should consider storing H1-Hn in a cell array (or normal array) so you can trivially loop over them.

%don't use this, but make sure to do something like this when the data is created
H={H1,H2,H3};PV={PV1,PV2,PV3};
for n=1:numel(H) 
    if j==1
        Tin(j)=20;
        Con(j) = H{n}(j)+Qel(j)*u(j);
        NL_(j) = Con(j) - PV{n}(j);
        
        Terr(j)=Ts(j)-Tin(j);
        u(j)=0;
        SOC(j)=0.5;
        if Terr(j)>=1
            u(j)=1;
        end
    end
end
