Hi there,
with V.6.0 I keep on with my experiment in translating a large C++
spin simulation program.

What I'm bouncing my head against today is the following:

there is a way in M to describe objects (matrices) having an arbitrary
number of dimensions, defined just at runtime?

In detail, I work on an orthogonal lattice where my spins are defined,
but the simulations require sometimes to deal with 1d (arrays),
sometimes more.

Yet I'd like to write the most general code it is possible, e.g. when
writing a procedure that - given a location in the lattice at the
coordinates {i,j,...} - returns a list of locations of the nearest
(in 1d: {{i-1},{i+1}}; in 2d: {{i-1,j},{i+1,j},{i,j-1},{i,j+1}} and so

thanks for any hint...
