[Gretl-devel] Re: different eigenvalue error handling for non-numeric input

... Merely in terms of what's easiest to achieve consistency, we could omit the current calls to gretl_matrix_na_check(). I can see a case for the opposite policy, namely generalizing this check, but that would involve more work and I'm not sure it would be optimal. Most of the time matrices don't contain any non-finite values, and we'd have to spend a bunch of cycles checking every element of big matrix arguments. Here's a thought. Not sure if it's worthwhile, but we could have a "set" variable that turns on NA-checking for matrix arguments. That would make it easier to determine where, in some complicated contexts, things first go wrong.
