removing elements of cell array

say I have a 1 column cell array

 x={'aa';'aal';'aalii';'aam';'aani';'aardvark';'aardwolf';'aaron'}

and word=nanny

how would I remove all words from the cell array that are not equal length to the word. For example. length(word)=5

remove all words from x that are not length 5

>> x = {'aa';'aal';'aalii';'aam';'aani';'aardvark';'aardwolf';'aaron'};
>> word = 'nanny';
>> x(numel(word)~=cellfun(@numel,x)) = []
x = 
    'aalii'
    'aaron'

Use your favorite internet search engine to locate the official MATLAB documentation for the functions that I used. MATLAB has really great documentation, and you will be doing yourself a great favor by learning to use it.

[William Smith]

If it's just explicit items you want to remove, rather based on a function, you can simply use 'setdiff'.

e.g.

setdiff({'one', 'two', 'buckle', 'my', 'shoe'},{'boot', 'my', 'shoe'})   
ans =
1×3 cell array
  'buckle'    'one'    'two'
