Hi Jacopo

What are you using to solve?  I ask as the PyAnsys Math application can dump out the matrices into Numpy and SciPy formats easily.  (It is using Mechanical APDL behind the scenes.)  

Otherwise see the pdf attached to the first link Tasos supplied.  And see the *DMAT, *SMAT, and WRFULL commands in the Mechancial APDL help.  WRFULL allows us to stop an analysis after assembling the full file if a actual solve is not necessary...though if you are comparing you'll need to do the solve anyway.
