How to save a variable within a for loop?

For a certain lon a lat:

days=13;
for indice=1:days
c1=max(max(u0(lon_useful,lat_useful,1,indice))); 
save('fev_fim_2019.mat','c1');
end

How can I save c1 without it being severe on the top each time i run the code?

I've tried :

save('fev_fim_2019.mat','c1(indice)');

But give me the following error:

Error using save
'c1(indice)' is not a valid variable name.

hello

what do you mean by "severe" ?? I don't understand the sentence :

How can I save c1 without it being severe on the top each time i run the code?

Your code overwrites the file 'fev_fim_2019.mat' in each iteration. What about collecting the data inside the loop and saving it afterwards?

By the way, this singular of "indices" is "index".

Maybe you can omit the loop:

days = 13;
c    = max(u0(lon_useful, lat_useful, 1, 1:days), [], 4); 
save('fev_fim_2019.mat', 'c');
