Linear Systems Solvers

The settings parameter linsys_solver defines the solver for the linear system. In C it corresponds to an integer OSQPInt (see c_cpp_data_types) and in the other high level languages to a string.

Solver	String option	C Constant	Integer value
QDLDL	“qdldl”	QDLDL_SOLVER	0
MKL Pardiso	“mkl pardiso”	MKL_PARDISO_SOLVER	1
CUDA PCG	“cuda pcg”	CUDA_PCG_SOLVER	2
