String of matlab script

Hi all,

Can you please help me to understand what does it mean: fprintf('\n%s.%s.%s\n', tt(5:6), tt(3:4), tt(1:2))

I don't know what tt means.... This string is about creation of filelist. I must understand how my script wirks but it's very difficult to me, because I'm not a programmist((((((((((

What's a progammist? Apparently they've played a lot of poker according to Google.

Wow, sorry(((((Sometimes I have to speak Russian in my lab and I changed it in my mind and in my brain((((

I mean programmer. I'm biologist.

Sorry))))))

It was very funny, when I read this)))

\n means new line %s means print a string tt can be a string,vector or array

When you say tt(5:6) you are selection elements inside tt, in this case it's element 5 and 6 where the numbers correspond to the index.

Example

tt='My Array'

tt(5:6) gives you the string 'rr'

Thank you so much)))))))

I understood it very easy)))

tt must be a string (an array of characters) previously defined in your code. What the code line does is display in console the elements of tt on reverse order and with a dot:

fprintf('\n%s.%s.%s\n', tt(5:6), tt(3:4), tt(1:2));
            ^  ^  ^        ^        ^         ^
            |__|__|________|        |         |
               |__|_________________|         |
                  |___________________________|

Try and run the following:

tt = 'aabbcc';
fprintf('\n%s.%s.%s\n', tt(5:6), tt(3:4), tt(1:2));

You will get the following result in console:

cc.bb.aa

Moncada-Torres illustrates how the code works, and gives a simpler code to explain what the code does.
