I couldn't find a command for this. Is it possible that does not exist for this every day problem?

I want to print     a_n   is  in  S .

Here are what I tried.

I have a two-variable matrixfunction A(x,y) with entries A_i,j(x,y).
I want to use mtaylor for each entries and the result to store in a matrix B.
Is it possible to do using the map command?
If not, what methods do exist?
(Instead of typing mtaylor for each entires.)

After typing

with(LinearAlgebra):
avector:=Vector(3,symbol=a):
bvector:=Vector(3,symbol=b):
'a x b'=CrossProduct(avector,bvector)
