Hi All,
I want to do something along the lines of:
for (i in 1:n){
for (j in 1:n){
A[i,j]<-myfunc(x[i], x[j])
}
}
The question is what would be the most efficient way of doing this. Would
using functions such as sapply be more efficient that using a for loop?
Note that n can be a few thousand. Thus atleast a 1000x1000 matrix.
Thanks,
Sachin
