Hello, users~!
I wonder what the algorithm is used in the calculation of inverse matrix of Octave.
I got a inverse matrix (complex number) with octave, however I failed to get a inverse matrix with my fortran code using umfpack.
The code of umfpack yielded non-exact inverse matrix, as the dimension of matrix becomes to large.
UMFPACK employed a LU decomposition, but I don't know what the kind of LU decomposition is used.
Where can I read the source code or algorithm of a calculation of inverse matrix of Octave?
Very thanks.
