How can I subplot heat maps?

I want to subplot heat maps, so I did as following but it didn't work. Please help me!

   A = [ 1 1 ; 2 2 ]
subplot(4,4,1)
HeatMap(A)

The HeatMap object does not support being displayed as a subplot. The new "heatmap" function introduced in R2017a supports this behavior

Thanks, my version is R2017a so maybe it's the reason.
