[Pysparse-developers] reading the source code of pysparse

[Oz N. T. <na...@gm...>]

Hi,

First, thanks for the great work on this peace of software. I have
been using it for more than 3 years now and I very happy.
I have a few question and I hope this is not
I am still very new to C programming and I was wondering what does the
following statement for expamle do:

n2b = F77(dnrm2)(&n, b, &ONE);/* Norm of rhs vector, b */

Is this some kind of type casting ?


The second question is, now that I have a working application with
pysparse that I'd like to accelerate,
I am thinking of rewriting my code in C. I know there are C solvers
for bicgstab, but I was wondering how
much work is it just to convert the bicgstab.c from pysparse to plain
C without the python dependencies.
Are there any hints here?


Thanks in advance,

Oz
