clear all;
img = imread('Image1.png');% Read secret image
ocr1 = ocr(img);
str = ocr1.Text;
str = lower(str);
out_str = regexp(str, '[a-z]', 'match');
count_occr = count(out_str, '[a-z]', 'IgnoreCase', true);
This is the code i tried

Use the ocr() function
txt = ocr(yourImage);

After using histcounts i got the following output
11 2 4 6 21 2 3 9 17 0 4 0 2 11 16 5 2 9 14 21 5 2 7 0 1
Is it possible to generate the Markov Matrix of this output.
