I am trying to create a contiguity matrix using Matlab - I have x,y coords,
and would like to create a (sparse) weights matrix of 0,1 for immediate
I've been trying to use the Spatial Econometrics Toolbox for Matlab, which I
guess is Pace and Kelley function - xy2cont, but for some reason it is not
working - it deletes one observation, so I end up with a non-square matrix.
Another person I know has had the EXACT same problem.
Has anyone used this toolbox? Is it buggy? The only inputs are two
matrices xcoord and ycoord, and it doesn't even work for a small sample I
Is there anything else out there, that anyone knows of? (e.g., Matlab
routines for creating sparse weights matrices?)
Any advice would be appreciated.
