F2PY has basic support for Fortran 90 module allocatable arrays.
请看示例Fortran 90 文件:
module modreal, allocatable, dimension(:,:) :: b
containssubroutine foointeger kif (allocated(b)) thenprint*, "b=["do k = 1,size(b,1)print*, b(k,1:size(b,2))enddoprint*, "]"elseprint*, "b is not allocated"endifend subroutine foo
end module mod
在dos窗口编译一下:
f2py -c -m allocarr allocarr.f90
下面演示在python中如何使用:
>>> allocarr.mod.foo()b=[1.000000 2.000000 3.000000 4.000000 5.000000 6.000000 ]
>>> allocarr.mod.b # b is Fortran-contiguous
array([[ 1., 2., 3.],[ 4., 5., 6.]],'f')
>>> allocarr.mod.b = [[1,2,3],[4,5,6],[7,8,9]] # reallocate/initialize b
>>> allocarr.mod.foo()b=[1.000000 2.000000 3.000000 4.000000 5.000000 6.000000 7.000000 8.000000 9.000000 ]
>>> allocarr.mod.b = None # deallocate array
>>> allocarr.mod.foo()b is not allocated
