But I don't have these vectors x and y, so I have to
create them just to call persp().
And persp also need
Well,
persp(x, y, z) does exactly what you asked for: it plots tha matrix z
along the values given by the vectors x and y.
If you need to calculate z values from x and y using some function foo,
outer(x, y, foo) is typically your friend.

Hello,
say I have a 2D-matrix (indexed by x and y), which contains
z values, which I want to plot over x-y.
Either dotted, or if possible as a landscape.
I tried around with persp and plot3d (from rgl)
and persp3d (from rgl).
I sometimes get something that looks good and a while later, when
