Hi,

I wrote a code that counts the number of occurences and I have to put it in a table with the alphabet as the first column. I can't figure out why the length of my vector is the same as the length of my string, and not as the length of the alphabet. The first 97 elements of vect_A were zeros (why?) so I suppose that this code won't work for a different string.

How can I create that table?

I would really appreciate if someone could correct my code and tell me what is wrong :

Here the code I tried :

s="In the golden lightning Of the sunken sun,Oer which clouds are bright'ning, Thou dost float and run, Like an unbodied joy whose race is just begun";
vect_A=[];
 
for letter=s(1:length(s));
    letter=lower(letter);
    for alphabet=['a':'z']
        A=count(s,alphabet);
        vect_A(alphabet)=A; %stock the value
    end
end
B=(vect_A(97:end))'
C=array2table(B)
