Have function to print matrix associated with checksymp() #7

Closed DavidSagan closed 5 months ago

This is helpful since looking at the significantly nonzero terms in this matrix gives clues as to where the non-symplecticity is happening.

Currently my checksymp returns 1-norm of transpose(M)JM - J. I'm thinking about instead making checksymp just return the matrix transpose(M)JM - J , and then the user could calculate the norm if it is to be a quantified as just a single scalar number. How does that sound?

Yes that sounds more modular. Do it.
