I have lists of matrices stored in various ways. I'd like to extend
%*% to work on these. Is this possible, or should I create my own new
operator?
A simplified example would be as follows:
A <- list( A1, A2, A3)
B <- list( B1, B2, B3)
where A1,...,B3 are all matrices, and I'd like A %*% B to return
list( A1 %*% B1, A2 %*% B2, A3 %*% B3)
In the real case A and B are sometimes arrays, sometimes something
else; lists haven't come up so far, but the principle should be the
same.
