Hi Georg, There is currently support for taking the matrix exponential of a symbolic matrix already in Sage since it is using Maxima in the background. I suppose that this should be extended to other types of matrices.
sage: matrix(SR, 3, 3, [[21,17,6],[-5,-1,-6],[4,4,16]]).exp() [ (13*e^16 - e^4)/4 (13*e^16 - 5*e^4)/4 (e^16 - e^4)/2] [ (e^4 - 9*e^16)/4 (5*e^4 - 9*e^16)/4 (e^4 - e^16)/2] [ 4*e^16 4*e^16 e^16] What functionality did you envision having in a symmetric matrix class? --Mike --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
