Exactly what are you trying to plot? What are the x values, and the y values?
You can't just string together three parentheses expressions like that
stackedplot ((output{1}(1:6480,:)(output{2}(1:6480,:)(output{1}(1:3600,:))
Try assigning each to some variable:
y1 = output{1}(1:6480,:)
y2 = output{2}(1:6480,:)
y3 = output{3}(1:3600,:)
Then use in stackedplot() and be sure to use commas between separate arguments.

stackedplot() does not offer any way to plot with different sizes of variables.
