I have written code to compute multi-indices in R [1] and due to the recursive nature of the computation I need to pass around the *same* matrix object (where each row corresponds to one multi-index). As pass by reference wasn't the default behavior I declared a global matrix (mat) and used the <<- operator to write to the global matrix. So the usage would be to call genMultiIndices(3,2)
