The following type of difference in behaviour, due to deterministic ordering of sets as introduced in Maple 12, may affect implementations of some algorithms.

I wonder what virtue there would be in an "assistant" in the Standard GUI to show and allow control of the interface settings.

In the absence of a built-in assistant (or tab in the Tools->Options panels) I wonder whether a simple Maplet would serve.

This is a follow-up to an earlier post about CovarianceMatrix.

There are several ways in which Statistics:-CorrelationMatrix can be improved.

CorrelationMatrix shares some inefficiencies with CovarianceMatrix, by computing correlations between the n columns, pairwise. But in doing so it also computes...

Some years ago, before the advent of the Statistics package, a colleague asked for a fast way to generate thousands of normally distributed random numbers in Maple. The suggestion that worked quickest and most easily (using existing, simple Maple Library routines) was to generate random deviates using the usual formula associated with the distribution. But the key was to replace the scalar values (representing the uniformly distributed input) with a whole Matrix of input values....

Every now and then someone will post here on Mapleprimes and the code will use an older package such as linalg or stats. Quite often it is clear that the poster is new to Maple. Yet these packages have been superceded with new ones, eg. LinearAlgebra and Statistics.

One obvious question that then arises is: how did this user decide to use the older package?

I just did a google search on
