writing a code involving struct

I have a file with a list of words, and what I want to do is to keep the words in such an arrangement where it will turn out like this letters='abcdefghijklmn......xyz'

wordbank.a=airplane
           aerosol 
wordbank.b=bulky
             big
             best
wordbank.c=..... ....

until 

wordbank.z=zebra ....
                 ....
                  ....

the whole code will be placed in a while loop, where every line in the word list will be processed and stored in the above arrangement. However I am not sure what is the right way of writing the code to make this happen.

Can somebody assist me with this?Thank you.

This page doesn't allow any space, therefore please know that the words are supposed to be kept in a [row,1] matrix

For fun, just take all the text from TMW website and sort them according to the first letter and then put them into a word bank.

words=urlread('http://www.mathworks.com');
words=regexp(words,'[A-Za-z]*','match');

for letter='a':'z'
    Wordbank.(letter)=words(strncmpi(words,letter,1));
end

'[A-Za-z]+'

would be a better search pattern: with the '*' it would also match the empty string, which occurs in _every_ line (including empty lines)

[Fangjun Jiang]

It won't result in empty string as it searches only for 'A' to 'Z' and 'a' to 'z'. I ran any(cellfun('isempty',words)) and it didn't find any. However, using '+' is better than '*' as there is no change of zero match.
