Creating a Loop for my work

Hi everyone,

I've got a old database, with folder with weird name that i have to rename to work on.

All my subject are named EC01 to EC50, and i've creating a code to change what i need to change on EC01:

"mkdir C:\Users\beber\Documents\EC01\RTC f

movefile C:\Users\beber\Documents\EC01\RTC\RTC_0034\graph* C:\Users\beber\Documents\RTC f

rmdir C:\Users\beber\Documents\EC01\RTC\RTC_0034"

And being new on Matlab, i wonder if there is a way to "loop" this code, to ask matlab to this manipulation on all the subject from EC01 to EC50 ?

Thank you for your help :D.

There is indeed! A basic loop runs through integer numbers that you specify. You can then convert these numbers to strings - which is matlab language for text.

Example:

for i=1:50 %whatever you write inside the for loop will execute 50 times, and each time the value of i will increase by 1
    
    numberstring=num2str(i); %now instead of a number e.g. 1, you have a string, '1'. 
    
    if i<10 %see below for why we do this! 
        
        mydir=['C:\Users\beber\Documents\EC0',numberstring,'\RTC f'];
        %the first time the loop runs, will be 'C:\Users\beber\Documents\EC01\RTC f'
        %the second time the loop runs, 'C:\Users\beber\Documents\EC02\RTC f'
        %the tricky part is, that obviously when you reach 10 you will get out 'C:\Users\beber\Documents\EC010\RTC f'
        %we get aroundn that by using "if" statements. 
        
        mkdir mydir; 
        %from there, make the rest of your code, and add more strings as needed. I wont make it all, play around with it a little bit - thats the best way to learn :)
        
       
        
    
    else
        
        filename=['C:\Users\beber\Documents\EC',numberstring,'\RTC f'];
        %small but subtle difference. Once i gets to 10, you will no longer put in the 0 before the number. 
        %so instead of getting EC010, you simply get EC10. 
        mkdir mydir;
     
    
        
end
