在python中调用fortran代码,要用到f2py这个程序。它的项目主页在此。现在该项目已经合并到numpy中了,先安装python再装好numpy,就可以使用f2py。不过对windows平台必须使用gnu的fortran编译器gfortran,在此下载。装完了python,numpy和gfortran这三样东西之后,还必须更改如下几个环境变量:
1.在$PATH中添加gfortran的路径,我的是c:\Program Files\pythonxy\mingw\bin\
2.在$PATH中添加python的路径,我的是c:\Python26\
3.新建环境变量C_INCLUDE_PATH,添加gfortran头文件的路径,我的是c:\Program Files\pythonxy\mingw\include\
好啦现在f2py就可以用了。新建fortran程序foo.f90如下
foo.f90
