outer(0:2, 1:2, "^")
[,1] [,2]
[1,]00
[2,]11
[3,]24
Is this what you want?

You could consider storing your data in 3d array.
If A and B are your matrices of first and second
numbers, respectively, with both being of the same
shape, then:
C <- array(c(A,B), dim=c(dim(A),2))
gives you a 3d array. For example,
C[,,1] is A
C[,,2] is B
C[2,1,] is the the v

All answers are "yes", but IMHO you are trying to be
too clever with your data structure. Programming is
*much* easier if you keep things simple.
Specifically:
(1) The function matrix() will happily build you
a matrix of type "list", with each element of the list
occupying one ce
