Editing tick marks figure

I'm trying to add extra tick marks to my figure for percentiles of my sample, but I got a little stuck on how to do it. My current tick marks are coded like this: xt=(0:30000:150000)'; xtl=sprintf('%d |',xt'); set(gca,'xtick',xt) set(gca,'xticklabel',xtl);

Now I would like to add three more tickmarks in (vector) variable PERC and label them respectively P25, P50 and P75. I think it should be easy to adapt xt: xt=[xt;PERC'] . However, I don't understand how to edit variable xtl. Can anybody help me out on how to do it?

xlim([0 200000])

xt=0:30000:150000;
xtl=compose('%d',xt);

PERC = [45000 100000 130000]; % say

xt=[xt PERC];
xtl=[xtl 'P25' 'P50' 'P75'];

[~,idx] = sort(xt);
xt = xt(idx);
xtl = xtl(idx);

set(gca,'xtick',xt,'xticklabel',xtl);

What I would've done in 2012:

xlim([0 200000])

xt=0:30000:150000;
xtl=strtrim(cellstr(num2str(xt(:)))).';

PERC = [45000 100000 130000]; % say

xt=[xt PERC];
xtl=[xtl 'P25' 'P50' 'P75'];

[~,idx] = sort(xt);
xt = xt(idx);
xtl = xtl(idx);

set(gca,'xtick',xt,'xticklabel',xtl);
