Numpy, BLAS, LAPACK, f2py
Hi, I have installed f2py on my system for wrapping existing FORTRAN 77 codes to Python. Then I have gone through the following steps An example for using a TLS (total least squares routine) http://www.netlib.org/vanhuffel/ 2) Get dtsl.f with dependencies 3) Run f2py dtsl.f -m foo -h foo.pyf only: dtsl \ \ \ \________ just wrap dtsl function \ \ \______ create signature file \ \____ python module name \_____ Fortran 77 code 4) Edit foo.pyf to your specific needs (optional) 5) Run f2py foo.pyf \_____________ this will create Python C/API module foomodule.c 6) Run make -f Makefile-foo \_____________ this will build the module 7) In python: Python 2.1.1 (#1, Sep 24 2001, 05:28:47) [GCC 2.95.3 20010315 (SuSE)] on linux2 Type "copyright", "credits" or "license" for more information.
Any suggestions to solve this problem ?
