txtisalpha = ismember(txt, ['a':'z', 'A':'Z']);

MATLAB: How to get the least used character in the text file

    %Sample text; equivalent to your a
    txt='this is a sample text.';
    uniqueChars=unique(txt(isletter(txt)));
    charCount=arrayfun(@(c) sum(txt==c), uniqueChars);
    % Now printing results
    fprintf('Char   count\n');
    fprintf(' %c     %d\n',[uniqueChars;charCount])
    fprintf('\nThe least Used Characters are:\n')
    fprintf('%c\n',uniqueChars(charCount==min(charCount)))
    fprintf('\nThe most Used Characters are:\n')
    fprintf('%c\n',uniqueChars(charCount==max(charCount)))

Once you run it you well get this:

Char   count
 a     2
 e     2
 h     1
 i     2
 l     1
 m     1
 p     1
 s     3
 t     3
 x     1
The least Used Characters are:
h
l
m
p
x
The most Used Characters are:
s
t
