I'm using surf to make 3d plots, but one of them comes out weird and I cannot understand why..thus is the figure that comes out:
even if the colormap on the right looks fine, the surface is completely black, even if I change 'FaceAlpha' and no matter how I rotate it...how can I fix this?

"how can I fix this?"
Two options:
  1. Don't plot so many points.
  2. Turn off the edge color.

Grid is too fine, set 'edgecolor' off.
surf(X,Y,Z,'edgecolor','none')

The set function has been around for quite a while (I believe it was introduced as a part of the original Handle Graphics system, but that's before my time at MathWorks.) It was and is permissive with respect to the case of graphics object property names.
The [object].[property name] syntax for Handle Graphics objects was introduced in release R2014b. Object property name indexing in general is case sensitive, and property name indexing for Handle Graphics objects is no exception.
