Given the name of the module iso_linalg_mod I wonder if the Fortran standards committee is thinking of adding such a module to the language. Is there a paper about this?
It might be nice to use the preprocessor to support single precision. Users can enable the preprocessor in the top-level fpm project according to their own needs, and choose to use iso_linalg_mod with single or double precision.
