Modified nodal analysis matrix from LTspice

I am working on a research problem that requires me to club inhouse MATLAB based electromagnetic (EM) simulation code with circuit simulation. The EM simulation algorithm used is finite-difference time-domain (FDTD). Is there a way to get the internal modified-nodal analysis (MNA) matrix for a circuit that I am solving for from LTspice?

Only if you can get the writer of LTspice to help you. I'm pretty sure that ADI will be unenthusiastic about helping you.
