How do I recover the renumbered mesh connectivity after using the symrcm function on my matrix?

Hello!
I'm trying to renumber my Finite element mesh, and I'm trying out the symrcm function implemented in MATLAB. I can get things working and symrcm dramatically reduces the bandwidth of my matrix.
My question is about recovering the mesh connectivity from the renumbered sparse matrix. Does symrcm provide a mapping between the old and new node numberings?
