Now that the new scipy.base (that can replace Numeric) is pretty much
complete, I'm working on
bringing the other parts of Numeric along so that scipy_core can replace
Numeric (and numarray in functionality) for all users.
I'm now using a branch of scipy_core to do this work. The old Numeric3
CVS directory on sourceforge will start to wither...
The branch is at
http://svn.scipy.org/svn/scipy_core/branches/newcore
I'm thinking about how to structure the new scipy_core.
Right now under the new scipy_core we have
Hierarchy Imports as
====================
base/ --> scipy.base (namespace also available
under scipy itself)
distutils/ --> scipy.distutils
test/ --> scipy.test
weave/ --> weave
We need to bring over basic linear algebra, statistics, and fft's from
Numeric. So where do we put them and how do they import?
Items to consider:
* the basic functionality will be expanded / replaced by anybody who
installs the entire scipy library.
* are we going to get f2py to live in scipy_core (I say yes)...
* I think scipy_core should install a working basic scipy (i.e. import
scipy as Numeric) should work and be an effective replacement for import
Numeric). Of course the functionality will be quite a bit less than if
full scipy was installed, but basic functions should still work.
With that in mind I propose the additions
Hiearchy Imports as
==========================
corelib/lapack_lite/ --> scipy.lapack_lite
corelib/fftpack_lite/ --> scipy.fftpack_lite
corelib/random_lite/ --> scipy.random_lite
linalg/ --> scipy.linalg
fftpack/ --> scipy.fftpack
stats/ --> scipy.stats
Users would typically use only the functions in scipy.linalg,
scipy.fftpack, and scipy.stats.
Notice that scipy also has modules names linalg, fftpack, and stats.
These would add / replace functionality available in the basic core system.
