How to add a colorbar in a heatmap?

Hey guys!

I am trying to do a heatmap, using a the heatmap function. But I am not being capable of adding a colorbar. Does anyone know if it is possible using the MATLAB version 2016a?

Also my current heatmap is like this, I would like to invert the beggining of the rows position. Is it possible that the row number 1 start on the first line not in the last one? And how could I eliminate the elements above the main diagonal?

Hello I see in the documentation the heat map introduce in r2017a, so I think you using heatmap from file exchange. I'm not sure if it's helpful for you,

h=heatmap(something....)
%then use this 
h.ColorbarVisible = 'on'

Yeah it didn't worked, due to the version I guess. But I was trying to do it in a different way, like this:

figure; 
imagesc(RPEARSONIDHma,[-1 1])
colorbar 
set(gca,'YTick', [1:11],'YTickLabel',{'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11'})
set(gca,'XTick', [1:11],'XTickLabel',{'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11'})
set(gcf,'Colormap',autumn)

Do you know if it is possible to make the values appear on the image?
