close all x = linspace(0,4*pi); y = sin(x); plot(x,y) axis([0 4*pi -1.2 1.2]) % Define y-ticks and their labels.. set(gca,’yTick’,-0.5) set(gca,’yTickLabel’,{’abc’}); %% this labels the y axis. %% now add another label set(gca,’yTick’,0.5) set(gca,’yTickLabel’,{’def’});
The problem is the command to set the new label deletes the previous labels and adds the new one. I want add a new label while retaining the previous labels. how to get that ???

There is no way to do what you want, even using the hold function. You have to combine the tick labels together in the same call:
x = linspace(0,4*pi);
y = sin(x);
plot(x,y)
axis([0 4*pi -1.2 1.2])
% Define y-ticks and their labels..
set(gca,'yTick',[-0.5 0.5], 'yTickLabel',{'abc', 'def'})

If you want to keep the original numeric ticks as well, the following will do that:
x = linspace(0,4*pi);
y = sin(x);
plot(x,y);
axis([0 4*pi -1.2 1.2]);
ytick = get(gca, 'ytick');
yticklab = cellstr(num2str(ytick'));
ytick = [ytick -0.5 0.5];
yticklab = [yticklab' 'abc' 'def'];
[ytick,ia] = unique(ytick, 'last');
yticklab = yticklab(ia);
set(gca, 'ytick', ytick, ...
'yticklabel', yticklab);

Not quite sure what you mean by maintain the order... something like this?
x = linspace(0,4*pi);
y = sin(x);
plot(x,y);
axis([0 4*pi -1.2 1.2]);
yTick = [0.1 0.2 -0.3 -0.5 0.4];
yTickLabel = {'ab' 'cd' 'ef' 'gh' 'ij'};
[yTick, isrt] = sort(yTick);
set(gca, 'ytick', yTick, 'yticklabel', yTickLabel(isrt));
