Array arithmetic

I think this should work:

array(A[abs(B) > 10e-5]/B[abs(B) > 10e-5], dim=c(L, M, N, P))
I have two arrays A and B with dimensions of (L, M, N, P) and (L, M,
 N), and I want to do

 for (i in 1:L) {
 for (j in 1:M) {
 for (k in 1:N) {
   if (abs(B[i, j, k]) > 10e-5)  C[i, j, k,] <- A[i, j, k,]/B[i, j, k]
   else C[i, j, k,] <- 0
 }
 }
 }

 How can I get C more efficiently than looping?

 Thanks,
 Gang
