Point Englobed In A Cube

Hi,

sorry for my bad English.

I've some random points in 3D space:

A=[21 55 55; 53 65 55; 61 51 11; 14 50 21; 58 49 22; 25 22 32; 10 0.2 21; 21 0.5 25; 55 88 90; 2.2 2 21; 4 7 11; 6 99 10; 7 8 9; 8 10 8; 1 57 15; 8 12 48; 1 27 98];

I've calculated the centroid:

cX=mean(x);cY=mean(y);cZ=mean(z);

Now, I would you like create (and plot) a CUBE that inglobe all points of matrix A. The CUBE must have follows features:

1. The cube must have the minimal volume that ALL points of A are internal

2. The CENTER of cube must match with the centroid [cX,cY,cZ] of points

The problem is simple but when you don't know well MatLab is all so difficult !!! =)

Thank,
