# Looking for software that computes intersection numbers (Heegaard Diagrams)

As a part of my research I am working with intersection matrices of Heegaard diagrams. Is there some software that could help me compute such matrices for some examples?

Thanks.

• Moira Chas has an applet to compute intersection numbers (although I couldn't get it to work on my laptop!): math.sunysb.edu/~moira Nov 1, 2013 at 22:06

More broadly, Nathan Dunfield curates the website www.CompuTop.org that is probably the first place to look if the question is: "Is there software (in low dimensional topology) that does $blank$?"
