Plotting a column of a matrix as function of the others

As the result of a computation, I have a Nx3 matrix (N is huge). The first column is called X, the second column is called Y and the third column is called Z. I want to plot Z as a function of X and Y, but there's no any particular order in the rows of the matrix and there might be repetitions. I would like to do two things:
1) Plot Z thridimensionally, as in a surface plot
2) Make a color map
How can I do this?
Thanks

make a meshgrid using values of X and Y
[x,y] = meshgrid(X,Y);
make a surfaceplot
surf(x,y,Z)
