[PYTHON MATRIX-SIG] linear algebra
Mon, 19 Aug 1996 09:38:35 -0400
I'm finally having some good success at putting together a standard
library for NumPy. There will be easy to compile, small C versions of
all the necessary Lapack and Blas routines available so that anybody
with a C compiler can use the standard lib. Now I have a question for
those people out there who use linear algebra more than I do.
All of the current interface routines (from LinAlg.py) do the following:
Should these two transpositions be there? This is obviously related to
the different index order between NumPy and FORTRAN. Still, I've always
personally considered it a superficial difference that is best ignored.
If I remember by Linear Algebra correctly
transpose(inverse(transpose(m))) == inverse(m).
However, I very rarely use any linear algebra functions in my code so
I'm not the right person to be making that decision. Opinions?
