Why not store them in a list, e.g.

> stt <- list()

[[1]]
     [,1]
[1,]    1

[[2]]
     [,1] [,2]
[1,]    2    2
[2,]    2    2

[[3]]
     [,1] [,2] [,3]
[1,]    3    3    3
[2,]    3    3    3
[3,]    3    3    3

There are no restrictions on the shapes of the matrices that can be
stored this way.  You access matrix i entry (j,k) as stt[[i]][j,k].
