Hi Baris,
I agree with your sentiments. Most people in PDL DO come from the
number crunching/scientific background.
I would say that a matrix is just a special case of a general
N-dimensional compact array which obeys various rules. PDL
supplies a matrix-mult operator ("x") and other matrix ops.
Note it is useful to have BOTH "x" and "*".
Our goal is to get true multi-dim arrays like PDL, as you say,
into the core. Then one would have matrices too.
What the prefix should be is of course as interesting question,
currently PDL uses $, @ could be used if overloading became possible.
Is there a real case for a special prefix?
