If you want to do a fancy matrix operation, you may need to invent the wheel yourself. Rmpfr only supports limited matrix operations. There may exist some C++ library that can do this job, I will suggest finding a matrix library whose elements are of a template type, then combine it with a multi-precision library so that you can do matrix operations in a very high precision.
