how to build a character array to show letters that appear multiple times in a word

[Image Analyst]

A simple example is needed. Do you mean a histogram of letter occurrences except that the bars in the histogram are the letters that each bar represents? I have no idea (other than that, which is probably wrong).

what i have right now is a simple dict that selects a rand word and reads in an input which is a letter. im trying to build an array that show letter inputs that appear multiply times in a word

Again "A simple example is needed."

Also, put this in the body of your post, which is missing right now, AFTER you read this link.

As I understand from your question, you want to build a character array of all those letters that appear multiple times in a word. For example if your word is 'mississippi', the character array should contain 'isp'.

The code for the above logic is

v = 'mississippi';
u = unique(v);
m = [];
for i = 1:length(u)
    if(length(strfind(v,u(i)))>1)
        disp(u(i))
        m = [m,u(i)]
    end
end
disp(m)
