Subarrays
Define an array
> v<-1:256
> dim(v)<-rep(4,4)
Subarrays can be obtained as follows:
> v[3,2,,2]
[1] 71 87 103 119
> v[3,,,2]
[,1] [,2] [,3] [,4]
[1,] 67 83 99 115
[2,] 71 87 103 119
[3,] 75 91 107 123
[4,] 79 95 111 127
In the general case this procedure is very tedious.
Given an array
A, dim(A)=(dim_1,dim_2,...,dim_d)
and two vectors
