|
|
Build extension module from a Fortran 77 source string with f2py.
|
|
|
|
Parameters
|
|
----------
|
|
source : str or bytes
|
|
Fortran source of module / subroutine to compile
|
|
|
|
.. versionchanged:: 1.16.0
|
|
Accept str as well as bytes
|
|
|
|
modulename : str, optional
|
|
The name of the compiled python module
|
|
extra_args : str or list, optional
|
|
Additional parameters passed to f2py
|
|
|
|
.. versionchanged:: 1.16.0
|
|
A list of args may also be provided.
|
|
|
|
verbose : bool, optional
|
|
Print f2py output to screen
|
|
source_fn : str, optional
|
|
Name of the file where the fortran source is written.
|
|
The default is to use a temporary file with the extension
|
|
provided by the `extension` parameter
|
|
extension : {'.f', '.f90'}, optional
|
|
Filename extension if `source_fn` is not provided.
|
|
The extension tells which fortran standard is used.
|
|
The default is `.f`, which implies F77 standard.
|
|
|
|
.. versionadded:: 1.11.0
|
|
|
|
Returns
