MATLAB: How to assign specific numbers (and letters) to the tick marks of a figure

axischesschessboardfigureMATLABtick

Coming off of my previous question, I've successfully generated by chessboard…but now I need to change the axes (you know, to the standard letter and number labels).
Searching through the answers here yielded something like
e.g.
set(gca,'ytick',[1 8]);
Problem is, doing this causes all the values along the y-axis to disappear.
And of course, the x-axis would require letters…so how should I go about doing that?
Oh, and my board looks like this at the moment:
I suppose that means that even if I do successfully relabel them, the values along the y-axis will essentially be the wrong way around. How do I reverse the order of the values then?

Okay, somehow managed to solve my problem thanks to both of you. Adam appears to be using an older version of MATLAB, but combined with Orion's solution it gave me the idea that led to me fixing my problem.
It's simply
xlab=zeros(rc,1);
for k=1:rc
   xlab(k)=96+k;
end
set(gca,'XTickLabel',char(xlab))
After the image has already been displayed. rc is the number of rows (or columns, since it's a square board).
p.s. With just this, if the board is too big the tick labels will get all wonky. Something like
if rc>11
   set(gca,'XTick',500*(1:rc))
end
might be required.
