Im trying to print out the last Alphabetic letter in a string.
For example S1 = '%@3Gb6kl@3G9@33G';
I want the letter G to get printed out.
Any help would be great :)

Your ‘S1’ is a string array, so you can use the end function to get the last letter:
S1 = '%@3Gb6kl@3G9@33G';
LastLetter = S1(end)
produces:
LastLetter =
G

Another way to get it printed out to the command window:
fprintf('%c\n', S1(end));

If x has the text. The next code extract the two lat letters
newStr = extractBetween(x,strlength(x)-1,strlength(x))

Ran in:
The question was about only the last letter, so you need a minor edit:
x="%@3Gb6kl@3G9@33G";
newStr = extractBetween(x,strlength(x),strlength(x))
newStr = "G"
x=char(x);
newStr = extractBetween(x,strlength(x),strlength(x))
newStr = 1×1 cell array
{'G'}
