If the x_i,y_i are indexes then look at PDL::Slices.
index1d applied twice, first for x_i and second for y_i?

Hi,
I would appreciate your help with this.
Let's say I have $data(X,Y,T) and a path running from x0..x1, y0..y1.
I would like to efficiently get the x-y data along that path for all t
(0..T-1). $path is a 2xN piddle. The result should be of size N x T.
Of course I can loop over path, but I thought there's a more elegant
solution with slice/dice, maybe?
Thanks
Ingo
