I’m not certain what the problem is.
You can get the handles to each subplot with:
Axsp = subplot(3,2,4); % Fourth Subplot Axes
for that particular subplot.
You then have access to that subplot’s properties:
Axsp.XLabel = 'NewLabel'
Axsp.XLabel.FontSize = 12;
Example —
figure
subplot(3,2,4)
plot((0:0.1:2*pi), sin((0:0.1:2*pi)))
xlabel('Time (s)')
ylabel('Velocity (cm/s)')
Then later —
Axsp = subplot(3,2,4); % Fourth Subplot Axes
Axsp.XLabel.FontSize = 12;
.
