Axis labels for subplot figure

Hi All,
I'm trying to place an x and y-axis label onto the figure centered horizonally (for x axis) and vertically (for y axis).
I've found a resaonable way to make the title using 'sgtitle' but nothing seems to exist for the lables, which is odd. How could I do this?
The current lines I have are copied below. I've commented out each of the subplot labels as I only need one for the entire figure.
Thanks!
%% Create a figure 2 x 6 (representing 12 months).

It uses the position of the existing plots to calculate the size (height and width) of a rectangle encompassing all plots in the window. It then uses the positions to place a new hidden axes over all the plots and adds a new x and y label to that axes.
In subplots, plots are filled in left to right, top to bottom. For the 2x2 example in the linked post, it would look like this
1 2
3 4
Height is the difference between the top position of the first row - the bottom postion of the bottom row. Using the information provided in position, this is p1(2) + p1(4) - p4(2).
- p1 could be any plot in the first row
- p4 could be any plot in the bottom row
Width is the difference between the right position of the last column - the left position of the first column. Using the information provided in position, this is p4(1) + p4(3) - p3(1).
- p4 could be any plot in the last column
- p3 could be any plot in the first column
With this info, you can now place the new hidden axes. Position is [left_edge bottom_edge width height]. P3 is used because it is the bottom left plot.
When adding the labels, you could do
axes(h5)
ylabel('test')
xlabel('test')
or
ylabel(h5,'test')
xlabel(h5,'test')
You really only need the position of 3 of the subplots
- Top left
- Bottom left
- Bottom right
You are plotting 6x2, so plots 1, 11 and 12.
