elegant matrix creation
Hello everybody.
I am trying to reproduce a particular matrix in an elegant way. If I
have
jj1 <-
structure(c(1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,
3,1,2,3,1,2,3,1,2,3,2,3,1,2,3,1,2,3,1,2,3,
1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,3,1,2,3,1,
2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,
2),.Dim = as.integer(c(9,9)))
[ image(jj1) is good here ] then I can get this with
kronecker(matrix(1,3,1),kronecke...
