[sage-devel] "Dynamic Galois Theory"

2009-06-15 Thread William Stein
Hi Sage-Devel, There is a talk right now at MEGA about "Dynamic Galois Theory" (lazy arithmetic in QQbar!). It's an IMHO horribly misnamed topic described here: http://hlombardi.free.fr/publis/GaloisDynamic09.pdf It's really basically how to use Groebner basis to do lazy computations in splitti

[sage-devel] Feature Request: element-wise multiplication of matrices

2009-06-15 Thread paramaniac
Dear Sage Developers, It would be very nice if Sage supported the element-wise multiplication of matrices like the .* operator in Octave/Matlab. EXAMPLE: sigma, tau, beta = var('sigma tau beta') A = matrix([[-1/tau, sigma/tau],[sigma/tau, -1/tau]]) B = matrix([[beta/tau, 0],[0, beta/tau]]) C =
