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.

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'
