Fortran magic
Compile and import Fortran symbols from a code cell, using f2py.
The contents of the cell are written to a .f90 file in the directory IPYTHONDIR/fortran using a filename with the hash of the code. This file is then compiled. The resulting module is imported and all of its symbols are injected into the user’s namespace.

Install
You can install or upgrade via pip
pip install -U fortran-magic
or directly from the repository using the %install_ext magic command:
In[1]: %install_ext https://raw.github.com/mgaitan/fortran_magic/master/fortranmagic.py
Basic usage
Once it’s installed, you can load it with %load_ext fortranmagic. Then put your Fortran code in a cell started with the cell magic %%fortran`. For example:
In[2]: %load_ext fortranmagic
In[3]: %%fortran
subroutine f1(x, y, z)
real, intent(in) :: x,y
real, intent(out) :: z
z = sin(x+y)
end subroutine f1
Every symbol is automatically imported. So f1 is already available:
In[4]: f1(1.0, 2.1415) Out[4]: 9.26574066397734e-05
See the documentation for details.
Changelog
0.4.2 / 2013-10-08
Implement the --extra option (Thanks to Denis Vasilyev for the help)
Include %%fortran’s args in the hashing, so the same cell are recompiled with the same code but different arguments
0.3 / 2013-10-03
Added %fortran_config to set and persist default arguments for %%fortran
Improve documentation
0.2.1 / 2013-09-24
