Hi,
I got 1000 NxN matrices grouped in one array. I want one matrix in which p_ij
is the average of all the 1000 matrices in the array. Here's what I'm trying to
do:
# P is the NxNx1000 array
for(i in 1:N)
for(j in 1:N)
for(k in 1: 1000)
mymat[ i, j ] <- mean( P [i , j , k ] )
Otherwise, I could have a NxNx1000 vector, and get the N^2 means of the 1+
(N^2)*(0: 999) elements. I don't know which is more efficient, but I wouldn't
know how to carry this last solution out anyway. Any ideas on how to do this
efficiently?
Thanks,
Dimitri
