clc;clear
Char = char(importdata('***.txt'));%Read characters from .txt file
Total = size(Char,2);
% Here, 2 --> if you have written characters in row.
% Use 1 instead of 2 if ypu have written in column.
Ascii = double(Char);
Unique_Values = unique(Ascii);
Counts = histc(Ascii,Unique_Values);
Probability_array = zeros(1,size(Char,2));
for i = 1: size(Char,2)
Instance = Char(i);
Instance_Ascii_Value = double(Instance);
Instance_Count = Counts(Unique_Values==Instance_Ascii_Value);
Probability_array(i) = Instance_Count/Total;
end
