Hello I am trying to graph 2 graphs side to side. this is my code creating both "frec" and "expectedProbabilities" bars but when I try b = bar(x,expectedProbabilities); does not work.
M = randi([0 1], 20, 2500);
M_sum = sum(M);
freq = accumarray(M_sum(:), 1, [20 1]);
figure(1);
bar(1:20, freq);
xlabel('Number of ones');
xlabel('Number of rows');
expectedProbabilities = zeros(20,1);
for i = 0:20
expectedProbabilities(i+1,1) = factorial(20)/(factorial(i)*factorial(20-i))*0.5^i*0.5^(20-i)*2500;
end
figure(2);
bar(expectedProbabilities);

combined = [freq, expectedProbabilities(1:20)];
b = bar(combined, 'grouped')
