I have the code approximately like this :
Word =[];
for m = 1 : N
Letter = read_letter(img, num_letters) %read_letter is the file function to correlate my .mat with character image(img) and then determining that img as a letter eg.('a','b' or 'c' ect.)
Word = [Word Letter];
So the question is. Are the values inside of Word variable are letters ? Additional:Does Word variable works like Unary Operation ?
Because i can't access this array to take its values with simple for loop like :
chars = ''; % i dont know whether this is necessary or nah
for m = 1 : length(Word)
if Word(m) == 'a' || Word(m) == 'b'
chars = 'character is a or b !';

"What does X = [X Y] mean"
It is a concatenation operator:
"Does Word variable works like Unary Operation ?"
How can a variable "work like" an operator?

I don't know exactly what read_letter does, but if it returns a character, then Word is a character array - basically a vector (1-D array) of letters.
If you need more help, attach
  1. your .mat file,
  2. your image file, and
  3. your code for the read_letter() function

OK. Not sure why you didn't get an email. It automatically does that. You might want to check your junk mail folder or check the email you have registered here to make sure it's right.
Thanks for doing #3 (attaching code). I'll get notified when you've done #1 and #2.
