[PYTHON MATRIX-SIG] Type Coercion

[Konrad HINSEN]

   a C plotting array that wants an array of C floats. You might even have
   an array of C floats but in general you don't know it is contiguous. It
   might be a slice of something else, or the result of any number of
   calculations that destroy contiguity (if that is a word!). 

Believe it or not, it is accepted by "spell" on my system ;-)

Contiguity might not be an issue when interfacing to Fortran code,
which can often handle non-contiguous arrays. Anyway, the C-API should
have the utility functions "copy if not contiguous" and "copy if not
sufficiently contiguous to be passed to a Fortran function". There
could be versions that include a cast.
