Plot values above of 0

I'd like to plot a 3d-graph (stem3) but using only values above of 0 matrix is arrangement

 0   25   3   5
 2   34   2   6
 0   56   0   3

so on I'd like to plot just values above of 0 Thanks

Do you want to keep the arrangement of the matrix in the stem plot? If so, one thing you can do is to set the 0s to NaNs

Let X be your matrix above.

    Y = X;
    Y(X==0) = NaN;
    stem3(Y)

Does that give you want you want?
