It was remarkable easy to make my plot package PyQwt for Numeric, also
compatible with numarray :-)
( PyQwt is a wrapper for Qwt, a Qt-based library with widgets useful for
science and engineering -- http://gerard.vermeulen.free.fr )
I discovered by accident that PyQwt compiled with
plots Numeric-arrays and that PyQwt compiled with
The only interface between PyQwt and Numeric (or numarray) passes through
PyArray_ContiguousFromObject to cast sequences into arrays from which data
is copied into Qwt's data structures.
PyQwt never returns Numeric- or numarray-arrays.
Is this feature platform dependent? Or is it safe to release PyQwt,
claiming that a Numeric-compiled PyQwt is compatible with numarray
