I try to plot two histograms and I need to know quantitavely what is the area and percentage of overlap of these two histograms.

Do the bins cover the same ranges? Like they're both 5 units wide and have edges in the same locations?

Assuming they do cover the same ranges... can anyone answer this question? I'm looking too!

I'd put each histogram into one row and take the min and the max.
bothHistograms = [hist1; hist2];
minCounts = min(bothHistograms, [], 1);
maxCounts = max(bothHistograms, [], 1);
Then get the ratio of the min value for each bin to the max value for each bin:
ratios = minCounts ./ maxCounts;
If you want the average percentage coverage over all bins, take the mean over all bins:
meanPercentage = mean(ratios);
