You can type dgeev to see its definition (coinsert 'jlapack2' so that
locale _jlapack2_ becomes optional)
It calls dll directly so that you may run the lab on ststem dllwin32 if you
are unfamiliar with calling dll.

The math/lapack addon was no longer supported on current J.
Instead, lapack is provided by math/lapack2. The windows binaries from it
has optimized blas,
should be order of magnitude faster than that in the older lapack addon.
However, usage of these 2 addons are different.

Dear J Jusers,
Earlier I used *LAPACK* in the *J602a* and *J804* versions without any problems.
I installed the *J903* version along with *LAPACK* based on

times, but it does not run,
it *always gives an error*.

Thanks for the suggestion, that indeed fixed it!
I don't remember doing this before, maybe I have a physical memory leak…
Even so, shouldn't this be handled by the installation of the package, or

It is mentioned in manifest of lapack but perhaps it cannot be shown in
android. It should offer advice as what you suggested.
If you installed addons inside qt demo, it will execute that command for
you.
pacman lacks post-installation script to execute extra commands.
