How to erase cell array element with less than three characters

If i have a function that accepts a string of characters eg('cgugcaguca') and i use

cellArr = regexp(mRNA, sprintf('\\w{1,%d}',3),'match');

to arrange the string into a cell array grouped in threes, how do i erase any elements with less than three characters.

eg {'cgu'} {'gca'} {'guc'} {'a'} , i want to erase the cell with 1 character.

Just specify the regular expression to only return groups of that number:

>> mRNA = 'cgugcaguca';
>> regexp(mRNA,sprintf('\\w{%d}',3),'match')
ans = 
    'cgu'    'gca'    'guc'

 C = [{'cgu'}  {'gca'}  {'guc'}  {'a'}] ; 
 
 L = cellfun(@length,C)  ;  % GEt length of each cell array 
 C(L<3) = []    % Remove cell's whose length is less than 3

Perfect, thankyou.

Hi, do you happen to know how I can remove all string/chars from a 4x10 cell array where each cell in that array contains a 40x1 column vector? (so as you can see, it's nested). Thank you :)
