baseline_values.mat

I currently have a table with monthly discharge values for 24 years across 11 varibles which I would like to convert to mean values for each Month - i.e. 1 mean value for each month (January, Febuary etc) for each variable. How would I go about doing this?

I will attach the data file if that is of any help. The end goal here is to plot regime graphs for each variable.

Something like this perhaps:

BV = table2array(baseline_values);
clf
subplot(2,1,1)
imagesc(reshape(BV(:,4),12,[])') % Illustrating with a random variable
subplot(2,1,2)
plot((reshape(BV(:,4),12,[])')')                     
hold on
plot(mean(reshape(BV(:,4),12,[])'),'k','linewidth',3)
Montly_avg(:,4) = mean(reshape(BV(:,4),12,[])');
