I want to compute the inverse of bothÂ L and L^T gotten from
gsl_linalg_cholesky_decomp(...).
1) What's the best way to a create bidiagonal matrix from the result
of gsl_linalg_cholesky_decomp(...) where the 2 matrices are store in
the matrix passed in?
2) What's the best routine to use to compute the inverse of L and L^T
separately? (I.e., I don't want to use
gsl_linalg_cholesky_invert(...), which gives me the inverse of the
original matrix.)?
