Use subplot() and title().
% Plot (a) plot.
subplot(3, 1, 1);
plot(1:10, 'r-');
title('(a)', 'FontSize', 15);
% Plot (b) plot.
subplot(3, 1, 2);
plot(10*sin(0:.1:10), 'b-', 'LineWidth', 2);
grid on;
title('(b)', 'FontSize', 15);
% Plot (a) plot.
subplot(3, 1, 3);
plot(cos(1:10), 'k*', 'MarkerSize', 15, 'LineWidth', 2);
grid on;
title('(c)', 'FontSize', 15);

Or you could use xlabel() if you want to put the letters under the x axis, or text() if you want to place them wherever you want.

I think Image Analyst's solution may need a bit more to get left alignment.

Personally, I've liked using:
nIDs = 4;
alphabet = ('a':'z').';
chars = num2cell(alphabet(1:nIDs));
chars = chars.';
charlbl = strcat('(',chars,')'); % {'(a)','(b)','(c)','(d)'}
text(0.025,0.95,charlbl{1},'Units','normalized','FontSize',12)
This works fine for me for tiled layouts, and does a decent job for scientific figures.

@Wiqas Ahmad Try using text() or put it into the title or axes labels using sprintf() and title() or xlabel() or ylabel().

Use legend()
legend('(a)','(b)','(c)')

No, legend is different. I want to label each graph as a,b,c etc. Like see in figure below generated through subplot function matlab, I want to label three graphs as a, b and c. try.png

I hope this function will help
fg = figure(1);
clf
subplot(2, 2, 1)
subplot(2, 2, 2)
subplot(2, 1, 2)
legend
colorbar
AddLetters2Plots(fg, 'HShift', 0, 'VShift', 0, 'Direction', 'TopDown')
