[julia-users] Dimension Independent Array Access

2014-11-17 Thread Christoph Ortner
I would appreciate advise how to best implement the following: I have an N^d array A, where the dimension d depends on the application (d \in \{1, 2, 3\}). Somewhere else I have a list L which is a d x M array or integers corresponding to points/elements in this array, e.g. if
