Re: [sage-devel] bug in matrix solve over inexact coefficients?

Although both behaviors may be reasonable, I don't like the fact that each line of the following code gives a completely different result depending on whether F = RR (returns a result that may be garbage, without warning) or F = RDF (gives an error, even though there may be a valid solution). M

Re: [sage-devel] bug in matrix solve over inexact coefficients?

Indeed, instead of ignoring the `check` keyword altogether over inexact fields, it would be useful to verify the solution when that is possible, such as for exact input over SR and for ball and intervall fields. I have opened #29729 for this. For general

Re: [sage-devel] Physics related tutorials

Dear Thierry, I was unaware of sagemanifolds web page. It already includes many decent GR related tutorials. When I was a MSc student I remember using Eric's lecture notes on 3+1 formalism in GR. You are right, perhaps it is best to write the tutorials first. Thanks for the advice. Best wishe

[sage-devel] Physics related tutorials

Dear All, My name is Furkan Semih Dündar. I am a new member of the group and a physicist in Turkey. So I would like to contribute physics related tutorials to the Sage web page. The topics may include classical mechanics (Lagrangian and Hamiltonian), quantum mechanics (matrix mechanics and the
