surface plot for matrix data

[Maximilian F. <mfa...@gm...>]

Hi,

is there a way to make gnuplot generate a "rendered" 3D surface or matrix-data?

I could convert the matrix data into x,y,z like files...henn I am
essentialy looking for somthing like
the MAXIMA's

M:MATRIX([1,2,3,4],[1,2,3,2],[1,2,3,4],[1,2,3,3])$
f(x,y):=float(M[?round(x),?round(y)]);
plot3d(f,[x,1,4],[y,1,4],['grid,4,4]);


Thanks,

Maximilian
