Use the Histcounts function to get the data and then apply correlation function to get the desired output

data1 = randn(1000, 1); %replace this with data for first histogram

data2 = randn(1000, 1); %replace this with data for second histogram

% Define the number of bins for the histograms

numBins = 20;

% Create the first histogram

[counts1, edges1] = histcounts(data1, numBins);

% Create the second histogram

[counts2, edges2] = histcounts(data2, numBins);

% Calculate the correlation coefficient between the two histograms

correlation = corr(counts1', counts2');

% Plot the histograms figure;

bar(edges1(1:end-1), counts1, 'FaceColor', 'blue');

hold on;

bar(edges2(1:end-1), counts2, 'FaceColor', 'red');

hold off;

legend('Histogram 1', 'Histogram 2');
