TODO: add min iteration criterion

it seems this example needs to be added to the added to SPHINX_GALLERY_IGNORE_PATTERN in root CMakeLists.txt

its because SymmetricMatrix redirects the accessor to the lower triangle: `return (i > j) ? (*getImplementation())(i, j) : (*getImplementation())(j, i) ;`

- we did test that the algorithms can be called recursively, see #85, but not in different threads - i print does works as expected in the C interface

@zaikunzhang, I just saw @emmt did mention scaling of the variables, I think the original f77 code did not do that, does prima do some kind of preconditionning now ?

yes, dont merge this one, go for https://github.com/yixuan/spectra/pull/152

weird, we have 3.12 wheel files for all 3 OS: https://pypi.org/project/openturns/#files what's the error message ?

I just re-checked, it works fine on linux+windows, are you sure its specific to OT/3.12 ? maybe pypi servers are blocked by the university firewall ? on mac, the arm...

need more info

it got better thanks to dill: https://github.com/openturns/openturns/pull/1677
