I am searching for a function that is equivalent to mathematica's MatrixExp, that will calculate the exponential of a symbolic matrix. I don't want a term by term exponential but a something like expm() in scipy but for symbolic matrices.
Is it possible in sage?
sage: m=matrix(SR,2,2)
sage: m.exp?
I get "No object 'm.exp' currently defined." Is it just my machine or it is not defined? Edit: Sorry about that it actually worked. Thanks
Just as a followup, since Sage 5.1.beta5, e^m will also work - see http://trac.sagemath.org/sage_trac/ticket/4735
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.

Though see http://trac.sagemath.org/sage_trac/ticket/12101, where trying to do this with sparse matrices causes problems.
