[sage-devel] Re: Is LinBox the default backend for sparse linear algebra over finite fields?

2019-02-23 Thread Travis Scrimshaw
Hi Mao, Right now in Sage, there is somewhat limited support for specialized sparse matrix operations, such as computing the echelon form. I believe the current algorithm for the echelon form is done using Sage's own implementation and does not take advantage of the sparsity. (You can

[sage-devel] Is LinBox the default backend for sparse linear algebra over finite fields?

2019-02-23 Thread Mao Zeng
It's the first time I post here. I don't know if sage-devel or sage-support is the more appropriate mailing list. How does Sage implement the method echelon_form() for sparse matrices over finite fields? Is LinBox the default backend? (I'm not a Sage developer, but would like to know about

Thanks, Eric. I never would have guessed that I could not use the most common notation in quantum mechanics! -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe from this group and stop receiving emails from it, send an email to
