You might use the r project with function poly2nb(queen=TRUE or queen=FALSE for the rock contiguity), in the library spdep (you see Applied Spatial Data Analysis with R .Roger S. Bivand, Edzer Pebesma and V. Gómez-Rubio Pág 240).

Other option is calculate in Geoda

Gustavo Henrique Dalposso

I agree with @Miguel.

Other option is calculate in Terraview

Cyril Fouillet

Below, you will find a link to a tutorial to calculate your matrix under GeoDa. Rook and Queen contiguity matrix can be created using GeoDa (as .gal files).

https://geodacenter.asu.edu/node/380#map

If you work with Stata, you can use spwmatrix command to import the .gal file as a Stata matrix.
