dataset unit testing conformance auxiliary functions.

[mu578]

Hello,

is someone have some standalone unit-test input/output dataset (error rate, expectation...) for auxiliary functions such as *lasq* family any help appreciated.

Thank you.

We do have a (Fortran) standalone test for the lasq family. We are mostly interested in accuracy and speed (in comparison with QR, for example). Is that what you mean by "error rate, expectation?"

Hello, thank you, ye, I am looking for a pre-computed set of diags of the bidiags matrices and their expected outputs; for instance, in q2 there is a comment about single and ieee (I suspect that a 3 epsilons machine precision would do it, instead of mostly assuming that radix is always 2) so, having already checked data would help to compare and verify.

If you have fortran test routines; I am interested in; however, nothing available here; + it took me two days to enter lasq "code", what a nightmare :). Maybe having Jacobi iterations and unrolled steps in shape of routines would be better; instead of having something organized by dimension.
