Terminate loop when condition is not met when save new file

Hello, I attempted to save a file every 18 days (by moving window) using a 'for' loop. However, Matlab continues to save new files when the condition is not met, how should the loop be terminated in 'for' loop? I tried using the 'break' condition, but it didn't work. The loop code is as follows:

for i = mjd(1) : mjd(end)
    
    hp2 = mjd_table(mjd_table(:,1) >= i & mjd_table(:,1) <= i+18,:); %sliding over 18 days
        
    name = sprintf('%d.txt',i+18); %rename over 18 days moving windows
        
    writematrix(num2str((hp2),'%.6f'),name);
             
end

It seems that the loop in your code is running continuously because you have not included a condition to check whether the current time window is greater than the end time of your data. To terminate the loop, you can add a check for this condition inside the loop using an if statement.

For example, you can modify your loop as follows:

for i = mjd(1) : mjd(end)

hp2 = mjd_table(mjd_table(:,1) >= i & mjd_table(:,1) <= i+18,:); %sliding over 18 days

name = sprintf('%d.txt',i+18); %rename over 18 days moving windows

writematrix(num2str((hp2),'%.6f'),name);

if i+18 >= mjd(end)

break; % exit the loop if the current time window is greater than the end time

end

end

In this modified code, the if statement checks whether the current time window (i+18) is greater than or equal to the end time of your data (mjd(end)). If this condition is met, the loop is terminated using the break statement.

I hope this helps!

This statement does, in fact, break the loop. Thank you incredibly much! Have a wonderful day!
