MATLAB: Find a letter position within a word.

matlab function

I need to right a function that will take in a word and a letter. Then return a list of all the positions in word where the letter exists. I need to figure out how to do this without using any built in functions. So far I have :
    function result = find_letter_positions(word,letter)
    indexes = [];
            for i = 1:length(word)
                  if word(i) = = letter
after this I am unsure of where to go

Best Answer

This might help you:

function indexes = find_letter_positions(word,letter)
indexes = zeros(1,numel(word));
for i = 1:numel(word)
    if word(i)==letter
        indexes(i)=i;
    end
end
indexes=indexes(indexes~=0);
end
