I created six plots. Each of this plot is created from a 4x3 matrix. The 12 values in this matrix are averages. Is there a way to add another 4x3 matrix for each plot, which contains the 12 standard deviations so that I can add error bars?
Thanks!

Ran in:
I do not understand what you want to do, although that is definitely possible.
Examples —
y = rand(4,3)*10;
err = rand(4,3)/5;
figure
errorbar(y, err)
grid
xlim([0 5])
figure
errorbar(y.', err.')
grid
xlim([0 4])
.
