how to count for whitespace symbol occurrences in a .txt file?

i found a way to read the .txt file and count the symbols using this code:

v=textread('FF7.m','%c'); count=length(strfind(v,'(symbol)'));

but i cant find a way to count the whitespaces, space, breaks, or tabs. in addition, since the input should be in script, i cant put the single quotation in the script. i also need to count the ' symbol.

can someone help me? any help will be very appreciated. thank you in advance!

Alternatively, you can use a simple regexp. It will certainly not be the most efficient solution though for this simple task:

 content = fileread('FF7.m') ;
 count = numel(regexp(content, '\s')) ;

EDIT: for counting ' only, you can do

 count = sum(content == '''') ;

If you wanted to count/sum whitespaces and ' with a single regexp call, you could do the following:

 count = numel(regexp(content, '[\s'']')) ;

'''' is a quoted single-quote.

You may wish to consider using ismember().

Also,

newline = sprintf('\n');
cr = sprintf('\r');
tab = sprintf('\t');
