Gaussian elimination on a TMatrix

ROOT
1

I have a “square” matrix, a system of 3 equations with 3 unknowns, that I’ve put into a TMatrix. Is there a ROOT method to perform Gaussian elimination on a TMatrix, so as to determine the values of the three unknowns? I understand ROOT uses Gauss-Jordan elimination to find the inverse of a matrix. Surely there’s a way to get just the solutions?

Please read tips for efficient and successful posting and posting code

Hi,
We have several decomposition methods in the TMatrix class for solving linear systems.
You can see here: https://root.cern/manual/math/#matrix-decompositions
a list of decomposition classes available in ROOT
