I want to count number of times first digit of first column is repeating. If
a = [11 3;
12 4;
13 3;
21 2;
22 5;
23 6;
24 3];
So, I want to get result in form of 1 = 3 and 2 = 4

Is that column guaranteed to be two-digit numbers, or could it be
a = [ 11 3;
121 4]
?

a = [11 3;
12 4;
13 3;
21 2;
22 5;
23 6;
243 3];
a1 = a(:,1);
firstDigits = floor(a1./(10.^floor(log10(a1))));
uniqueFirstDigit = unique(firstDigits);
firstDigitCount = histcounts(firstDigits,[uniqueFirstDigit; Inf])'
