Add label to sub-axes in plotmatrix

I am using the plotmatrix function and would like to label the sub-axes (along the major Y axis and X axis only, of course). I've managed to turn all the YTickLabels and XTickLabels off:
set(AX,'YTickLabel',[]);
but cannot figure out how to change the current axes from BigAx to the required subaxes in AX. I can manually add the labels using plotTools, but there must be a way to do this using code? I have a large-ish matrix (10x10 minimum) so it would a real help to be able to write a script to do this. Please help!!

Just in case anyone is interested,
ylabel(AX(1,1),'str1')
ylabel(AX(2,1),'str2')
xlabel(AX(8,1),'str3')
xlabel(AX(8,2),'str4')
does the trick.

The above suggestion doesn't work. This does.
X = randn(50,3);
Y = reshape(1:150,50,3);
[~,ax]=plotmatrix(X,Y);
ax(1,1).YLabel.String='Test1';
ax(2,1).YLabel.String='Test2';
ax(3,1).YLabel.String='Test3';
ax(3,1).XLabel.String='Test7';
ax(3,2).XLabel.String='Test8';
ax(3,3).XLabel.String='Test9';

Ran in:
To save time, I recommend labeling the sub-axes programatically using a for-loop:
% Let's say you have the following data table
variable_names = {'Dog','Cat','Bird','Fish','Goat','Man','Bear','Pig'};
rng(0)
data_table = array2table(10.*randn(60,8)+50,'VariableNames',variable_names);
% Use plotmatrix to visualize the data and add axis labels with a for-loop
[~,ax] = plotmatrix(data_table{:,:});
iterations = size(ax,1);
for i = 1:iterations
ax(i,1).YLabel.String = variable_names(i);
ax(iterations,i).XLabel.String = variable_names(i);
end

To create a sublabel on plotmatrix (on the outer subplots) use something like the following... The suggested answer above doesn't work.
X = randn(50,3);
Y = reshape(1:150,50,3);
[~,ax]=plotmatrix(X,Y);
ax(1,1).YLabel.String='Test1';
ax(2,1).YLabel.String='Test2';
ax(3,1).YLabel.String='Test3';
ax(3,1).XLabel.String='Test7';
ax(3,2).XLabel.String='Test8';
ax(3,3).XLabel.String='Test9';

Thanks for sharing this code, I have a correlation plot with 14 variables.. I need to place all the lables.. but there is no enough space..
I've tested figure and label properties but they dont work..
How to modify this string type lables; for instance changing their orientation or font size..
