components#
ipc_ status
return status. See LSQP_solve for details
ipc_ alloc_status
the status of the last attempted allocation/deallocation
char bad_alloc[81]
the name of the array for which an allocation/deallocation error occurred
ipc_ iter
the total number of iterations required
ipc_ factorization_status
the return status from the factorization
int64_t factorization_integer
the total integer workspace required for the factorization
int64_t factorization_real
the total real workspace required for the factorization
ipc_ nfacts
the total number of factorizations performed
ipc_ nbacts
the total number of “wasted” function evaluations during the linesearch
rpc_ obj
the value of the objective function at the best estimate of the solution determined by LSQP_solve_qp
rpc_ potential
the value of the logarithmic potential function sum -log(distance to constraint boundary)
rpc_ non_negligible_pivot
the smallest pivot which was not judged to be zero when detecting linear dependent constraints
bool feasible
is the returned “solution” feasible?
struct lsqp_time_type time

struct fdc_inform_type fdc_inform
inform parameters for FDC
struct sbls_inform_type sbls_inform
