The documentation for the function `gsl_linalg_LU_refine` states the following: " ... The initial residual r = A x - b is also computed and stored in residual".

Analysis of the source code indicates that this is not the case. The vector `residual` contains an intermediary result.

Online documentation: https://www.gnu.org/software/gsl/manual/html_node/LU-Decomposition.html
