2012-06-22 05:27:17 +0200	answered a question	Is it possible to find the exponential of a symbolic matrix using sage? Would this work for you? `A = matrix(SR, 2, var('a,b,c,d')) exp(A)` I get a long expression which I assume is the matrix exponential.

2012-06-19 07:02:57 +0200	asked a question	Compiling Sage with multiple cores Hi all, I am compiling Sage 5.0.1 in Ubuntu 12.04 According to the book "Sage: Beginner's Guide" to compile with multiple cores one needs to export a variable MAKE. I did so `export MAKe="make -j7"` and everything went well until the Atlas-3 compilation started. While compiling this (which is painfully big) only 1 core is being used. Is there a way to compile all the parts of sage with multiple processors? Thanks
