Hello, in the code below I am attempting to do the following:
yourarray = ['hood'; 'hope'; 'make';];
guess = input('Enter a four letter word: ');
yourarray(ismember(yourarray, 'guess', 'rows'), :) = [];
disp(yourarray);
  1. Take in user input for a four letter word
  2. Remove the four letter input from the matrix then display the resulting matrix with the user input removed
I have had no luck. I am trying make it so that I can remove any sequence letter the user chooses for instance, instead of one of the three words in the matrix he may choose "mope". How can I better accomplish this? Any advise is greatly appreciated. I have tried other methods but landed on this one as being what I think will be the closest possible solution. Thanks for any help!

Try this:
yourarray = {'hood'; 'hope'; 'make'}; % Cell array.
guess = input('Enter a four letter word: ', 's'); % Use 's' option.
index = ismember(yourarray, guess, 'rows')
if all(index == 0)
% All zeros mean it was not found.
message = sprintf('%s was not found in the list.', guess);
uiwait(warndlg(message));
else
% If any element of index is 1 then it was found at that row.
row = find(index)
yourarray(row, :) = [];
celldisp(yourarray);
end

No the letters can be found and combined from anywhere in the block. That is the basis of the game to find hidden four letter words in a scrambled block of letters.

And what about my first question in my last comment?
