[R-sig-Geo] Repeat columns and rows of matrix

[az14]

Dear list, 
i have a matrixW(1060*1060), i want to repeat each column and row 9 times,
such as to have a new matrix W1(9540*9540).
I use the code: 
rep.row<-function(x,n){
   matrix(rep(x,each=n),nrow=n)
}
rep.col<-function(x,n){
   matrix(rep(x,each=n), ncol=n, byrow=TRUE)
}

ww<-rep.row(w,9)
W1<-rep.col(ww,9)

but i did not work! 

Is there another way to do it ?

Any help would me appreciated. 
Thank YOU.
