components

Int32 status

return status. See LSQP_solve for details

Int32 alloc_status

the status of the last attempted allocation/deallocation

NTuple{81,Cchar} bad_alloc

the name of the array for which an allocation/deallocation error occurred

Int32 iter

the total number of iterations required

Int32 factorization_status

the return status from the factorization

Int64 factorization_integer

the total integer workspace required for the factorization

Int64 factorization_real

the total real workspace required for the factorization

Int32 nfacts

the total number of factorizations performed

Int32 nbacts

the total number of “wasted” function evaluations during the linesearch

T obj

the value of the objective function at the best estimate of the solution determined by LSQP_solve_qp

T potential

the value of the logarithmic potential function sum -log(distance to constraint boundary)

T 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?
