Hi,consider this with gretl 2025a: <console> ? matrix hello = {1/0} # to get invalid input ? = eigensym(hello) Not a Number geschah bei Berechnung ? = eigen(hello) 1.#INF ? = svd(hello) nan </console>So we have everything: a hard-stopping error, some IEEE code (?), and a gretl code. Plus, with a 6x6 matrix input I also saw that eigen() spat out a "Data error".
Ouch
I think it would be good if this could be a little harmonized, no?
Is it even possible to do without breaking backwards compatibility? I we don't care about that, I'd favour stopping with an error rather than returning NAs (FWIW, stopping with an error is what both Octave and R do).
