MATLAB: Removing elements of a cell array

cells arrays strings

say we have a cell array

dictionary= 'abbreviately' 'abbreviation' 'abbreviator' 'abbreviatory' 'abbreviature' 'abby' 'abcoulomb' 'abdal'

I have written a code which returns x = 0 0 0 0 1 0 0

word='saddest'
newguess='e'
 x=newguess==word

How do I delete the words from dictionary that are not equivalent for my x value and newguess letter 'e'. So x has a true value on the 5th position (after the 4 false values), which would mean I would like to delete all the words from dictionary if their 5th position letter does not equal 'e'. Thank you

newdictionary = C( cellfun(@(C) length(C) >= 5 & C(5)==newguess, dictionary, 'Uniform', 0) );

MATLAB: Deleting words from a cell array

x={'areach';'aread';'areal'; ...
   'areality';'arean';'arear'; ...
   'areasoner';'areaway';'areca'; ...
   'arecaceae'};
y='a';
word='areach';
% This line does the trick;
x=x(cellfun(@(c) all(c(find(word==y))==y),x))
x = 
      'areach'
      'aread'
      'areal'
      'areality'
      'arean'
      'arear'
      'areasoner'
      'areaway'

Note that the position 1 and 4 are not hard coded. They are defined based on the y and word

MATLAB: Searching for specific word containing specific letters and removing last element in the string

For the first part of your question:

wordlist = {'airplane', 'ball', 'bell', 'bull'};
letters = 'a':'z';  % a, b, c, ..., z
wordstruct = struct;
for ichar = 1:length(letters)
  wordstruct.(letters(ichar)) = cell.empty;
end
for iword = 1:length(wordlist)
  wordstruct.(wordlist{iword}(1)){end+1} = wordlist{iword};
end

I have no idea what you are asking in the second part. Maybe something like:

x = wordlist;
for iword = 1:length(wordlist)
  if strcmp(wordlist{iword}(end), 's')
    x{iword} = wordlist{iword}(1:(end-1));
  end
end
