So, I'm trying to learn how to write Pyrex code. So far, I've been able to
fit some functions into existing files, but creating new files and modules
to Sage has been difficult...
I'm moving polynomials to sage.rings.polynomial because there are getting to
be a fair number of files for polynomials. I'm then creating a padics
folder inside there.
I'm also creating a padics folder in sage/matrix.
In addition to moving some files around, I'm writing new matrix and
polynomial classes. The polynomial class is pure Python, and I think I have
it mostly working. The matrix class however...
Does anyone know where I can find some tips on writing .pxd files? What do
I need to include, import, cimport, from blah cimport, cdef, cdef extern,
etc.
Also, I'm trying to add a function to the Matrix_integer_dense class and
getting an error embedding the pyrex code. I've included the .pxd file
below (I moved the arrow to where it actually points to for those of us
without fixed-width fonts). If anybody could point out what I'm doing
wrong, I'd appreciate it.
