Need a quick help on storing words according to lengths with struct

Given a wordlist in cell array

wordlist={'blues';'rhyme';'armor';'dinosour';'book';'mail'......};

wordstruct=struct;

%%i am not sure how to proceed however it is organised such that the words are between four to 25, and I would like to do something like this,

wordstruct.4L={book mail ....}

wordstruct.5L={blues rhyme.....}
.

.

.

.

.

wordstruct.26L={whateveritisthatmightexist}

I almost given up on finding the right way to do it this way. Any help is very appreciated!

You have to use wordstruct.L4, wordstruct.L5, etc. as '4L','5L' etc. are not valid name.

cellfun('islength',...) and then a for-loop should getting you there.

wordlist={'blues';'rhyme';'armor';'dinosour';'book';'mail'};
clear wordstruct;
Len=cellfun('length',wordlist);
for L=4:26
    wordstruct.(['L',num2str(L)])=wordlist(Len==L);
end

I do realize that it is not a valid name, but I am not sure how should I change it. For your information, there will be at most 250k of words and i have to sort the words according to their word length and later, find out how many words have a certain word length.

I am not sure why but the function cell2str is not defined in the matlab program. Perhaps its been updated to a different function name?

[Fangjun Jiang]

Sorry, I meant cell2struct(). In fact, it doesn't have to be used. See update.
