The subject line is from http://www.math.utah.edu/lab/ms/matlab/matlab.html
I've seen little use of the words "matrix" or "vector" in the numarray
stuff. These are one or two dimensional structures.
The Numeric/numarray focus is on multidimensional arrays.
Some years ago, Huaiyu Zhu made a number of postings advocating the
introduction of a Python-based system permitting the usual matrix
operations. It seems that the culmination of these efforts was Matpy
(http://matpy.sourceforge.net/), which is not currently active.
I was impressed with the case made by Huaiyu Zhu and have attempted to
carry on in this direction. An outline of this work is at:
This work was based on numarray, partly because it was generally
considered to be the way ahead and partly because it purported to
provide a class structure. numarray has proved to be a bit of a moving
I am continuing this work in the hope that some class-based structures
will come out of the current Numeric3 discussions. The hope is also
that there is a need out there for matrix operations, as distinct from
