# FN_PARALLEL_REDUNDANT

In matrix function evaluation, all processes compute redundantly.

## Note

When this parallel mode is selected, all processes will make the computation redundantly, starting from the same data, and producing the same result. This result may be slightly different in the different processes if using a multithreaded BLAS library, which may cause issues in ill-conditioned problems.
