How to plot a 3D picture

Hi,

Suppose I have a 4 by 4 matrix as following:

10 6 3 1

 8 4 3 2

 6 2 4 3

 9 3 4 2

The x axis is the column index of the matrix, the y axis is the row
index of the matrix and the z axis is the value in the corresponding
position of the matrix.

I tried to use contour and image. They are not the ones I want.
