How to remove some xticklabels (but still keeping all the xticks)?

How can I remove some xticklabels, but still keeping all the xticks?

Let's consider the following example:

x = 1:100;
y = exp(-0.1*x);
plot(x,y)

I want to remove the xticklabels corresponding to "0", "10", "20", "30", getting the following plot:

How can I do it?

I tried the following, without success:

ax = gca;
ax.XTickLabel(1:4) = '';

x = 1:100;
y = exp(-0.1*x);
plot(x,y)

ax = gca;
ax.XTick = 0:10:100;
ax.XTickLabels(1:4) = {''};

x = 1:100;
y = exp(-0.1*x);
plot(x,y)
xticks(0:10:100)
xl = xticklabels;
xl(1:2:end) = {''}; % Replace every other label
xticklabels(xl)
