Multiple matrix multiplication with two 3-dimensional arrays
Hi,
I need to do several matrix multiplications with
the corresponding matrices forming two
3-dimentional arrays. To illustrate my problem,
let's say I have the following 3-dimensional arrays:
array1 <- array(1:30,dim=c(3,2,5))
array2 <- array(1:20,dim=c(2,2,5))
I know that I can get what I want with the following computation :
result <- array(dim=c(dim(array1)[1],
