I have about 100 points data, they form a perfect cube. How can I draw surfaces through these points to connect them and form a solid shape on Matlab?
Thanks,

P=randn(100,1);

It depends. There is a very large number of possible surfaces through 100 points. So you have to decide for one. It could be e.g. the convex hull, or you can use the information that the points are comming from a cube and determine the smallest cube, which contains all points (attention: this must not be unique). Or you can create an hull, which is convex considering all points in a certain distance only (this would e.g. allow a cube with a cyclinder shaped hole through the center).
The decision to a specific surface depends on your needs. How it can be displayed afterwards might be a proper question for the forum.
