I want to describe the graphs in figure caption by referencing them as (a), (b) (c) etc

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.

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().

You can make the label generation shorter using:
charlbl = compose("(%s)",('a':'z').');

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

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')

Personally i found my optimum with the following solution:
ax=gca;
% read out the position of the axis in the unit "characters"
set(ax,'Units','characters'); a=get(ax,'Position');
% this determines the type of the plot
if isequal(get(ax,'View'),[0 90]) % this is used for 2D plots
str_place=2;
else % this is used for 3D plots, in this case also all other plots
str_place=-2;
end
% this sets an 'a)' right at the top left of the axes
text(ax,0,a(end)+str_place,'a)','Units','characters')
I specifically used the units "characters" here, because it consistently sets the character above the axes indepently of the actual size of the axis. The latter is difficult if not impossible to do with "units", "normalized".
