One may use FINDOBJ to locate all subplots/axes on a figure and then use a FOR loop to label/title all the subplots. For example:

f=figure;
subplot(2,2,1:2)
text(.5,.5,'subplot(2,2,1:2)',...
    'FontSize',14,'HorizontalAlignment','center')
subplot(2,2,3)
text(.5,.5,'subplot(2,2,3)',...
    'FontSize',14,'HorizontalAlignment','center')
subplot(2,2,4)
text(.5,.5,'subplot(2,2,4)',...
    'FontSize',14,'HorizontalAlignment','center')
ax = findobj(f,'Type','Axes');
for i=1:length(ax)
    ylabel(ax(i),{'Nice'})
    title(ax(i),{'Very Nice'})
end

Hope this helps.

Since all of your subplots have the same labels, I would label only the left subplots for y-axes and bottom subplots for x-axes. This way your plots look a little bigger because your labels don't take extra space.

Thank you!

I may use anywhere between 2-4 subplots and I wanted the title only once. I used

demo1=figure(1);
plot(x,y)
ax = findobj(demo1,'Type','Axes')
title(ax(length(ax)),'my Title')

Note the index of 'ax'. I have used the last one because it gets the axes in the reverse order. If you use ax(1), the title will be on the last subplot.

FigH     = figure;
subplot(1,2,1);  subplot(1,2,2);
AxesH    = findobj(FigH, 'Type', 'Axes');
YLabelHC = get(AxesH, 'YLabel');
YLabelH  = [YLabelHC{:}];
set(YLabelH, 'String', 'Y-label')
TitleHC  = get(AxesH, 'Title');
TitleH   = [TitleHC{:}];
set(TitleH, 'String', 'The title');
