I have a 2D matrix and I want to plot a heat map. I use the following codes:

fig = surf(X,Y,F);
set(fig,'linestyle','none')
view(2)

But it displays just a plan entirely blue despite the large difference between Z values as shown in image below. How can I fix this issue?

I ran the code again and plotted some data tips, and the output is still different from what you got.

Check the image attached.

That's fine.

Thanks for your time and consideration
