Put a variable in a file title name

Hello,

I want to run a for loop that has an id=1:100 and at the end of each iteration I want matlab to save the results under a file name "Trace_id". So at the end of the programe I will have files called Trace_1 , Trace_2 ,etc...

Thank you

Use the sprintf method shown here:

Something liks this

for id=1:100
    % do your processing
    M; % matrix to write to file
    filename = sprintf('Trace_%d', id);
    writematrix(M, filename)
end

Maybe, either i or id throughout but not both. Another way

filename=strcat('Trace_',num2str(i));
