Re: [Lapackpp-devel] Solving a linear system with 100 unknowns

[Dee <de...@de...>]

Hello Sivahari,

not that I'm aware of. I have programmed it manually in my Ph.D. thesis
with the help of lapackpp. That means I got my input parameters, created
a Least-Square matrix, solved it and extract the values for my
line/polynom/spline (the latter in my case).

Best regards
Dominik
