XTicklabels don‘t match

I am plotting a matrix using below code.
The XTicklabels are supposed to be labeled per tick, but they only label every second tick.
Does anybody have a solution?
a = [12 16 5 5 5 11 4 4 3 3]; % rock data
b = [1 1 1 1 2 2 2 2 2 4]; % image data
u = union(a,b);
[~,ia] = ismember(a(:),u);
[bb,ib] = ismember(b(:),u);
n = length(u);
c = accumarray([ia(bb),ib(bb)],1,[n n]);
csum=sum(c,2);
d=c./csum;
% plot the results
figure, clf
x=u';
ytmp=flipud(u); % flip y-direction
y=cellfun(@(x) num2str(x),num2cell(ytmp),'UniformOutput',0);
pcolor(d)
colormap jet
colorbar
set(gca,'XTickLabel',num2str(x))
set(gca,'YTickLabel',y)
xlabel('Image code')
ylabel('Facies code')

But attention: this is not bug see Rik's answer about set Xtick

If you want full control over the ticks, you must set both the ticks and their labels explicitly. If you don't, it may depend on your resolution if you get your desired result. You can easily check this by resizing your figure window. This has been the case since before HG2 as far as I know.
set(gca,'XTickLabel',num2str(x)),set(gca,'XTick',1:numel(x))
set(gca,'YTickLabel',y),set(gca,'YTick',1:numel(y))

The trickiest bugs to find are those where you write something on autopilot yourself and don't realize someone else didn't.

This is a great answer. It has saved me hours of debugging thanks to your solution Rik. Thank you!
