Core dump when using the rational leastsquare and quadprog plugins
Summary
I tried to fit a 1D dataset with a rational function using different fitters. I ended with a core dump with the leastsquare and quadprog plugins.
Reproduce
Here is the commands I used to get the core dump:
data2brdf --input ./sources/tests/Kirby2.dat --output linear_space.func --fitter rational_fitter_quadprog
However, the following command works fine:
data2brdf --input ./sources/tests/Kirby2.dat --output linear_space.func --fitter rational_fitter_eigen
