For standard axes, the title property is a Text object, so properties such as Interpreter and FontSize can be setted directly.
However it seems that for heatmap objects, the title property is just a string.
Is there any way to modify the title properties? (for example setting the Interpreter to latex)
(The same applies also to XLabel and YLabel)

Matlab's heatmap() function (released 2017a) is notoriously difficult to customize. The handles to the title and axis labels are not accessible. You can follow the advice in this answer which shows how to overlay an invisible axes on top of the heatmap where you can customize the title and axis labels as you normally would.

@Daniel,
Check out these 3 alternatives to heatmap and 2 more examples. These alternatives avoid the restrictions of heatmap().
Now let's turn that frown upside down!
% rotating frown face
fig = figure('Units','Points','Color','w','menu','none');
sz = 200;
fig.Position(3:4) = [sz,sz]*1.2;
movegui(fig)
ax = axes(fig,'Units','Normalize','Position',[0 0 1 1]);
axis(ax,'off')
axis(ax,'equal')
xlim(ax,[-1,1])
ylim(ax,[-1,1])
hold(ax,'on')
scatter(ax,0,0,sz.^2,'y','filled')
txh = text(ax,0,0,char([55357,56897]),'HorizontalAlignment','Center',...
'VerticalAlignment','middle','FontSize',sz*1.13); % Helvetica, Windows 10.
while isvalid(fig)
txh.Rotation = txh.Rotation - 2;
drawnow; pause(.01)
end

I can't remember where I originally found this solution but I needed this just now and found it in one of my scripts. To access and change the property of title, axis labels etc. use for example:
h=heatmap(...)
set(struct(h).Axes.Title,'FontWeight','normal')
Matlab will throw a warning but it works fine.
