I have a set of, say 36 observations and wish to calculate the distance matrix for these observations. Now I can do so with the use of a double do-loop, but this seems tedious (even though, for my purposes at this stage, computation time is negligible still). I read that the "distance" operator can be used in this way:
delta = distance(matrix, "L2");
for, say, the Euclidian distance. It seems like a nifty function, unfortunately on my SAS9.3 system, the log gives me an error saying "Invocation of unresolved module DISTANCE."
Anybody have an idea why this is?
