components

Int32 status

reported return status:

• 0

  the solution has been found

• -1

  an array allocation has failed

• -2

  an array deallocation has failed

• -3

  n and/or Delta is not positive

• -10

  the factorization of \(K(\lambda)\) failed

• -15

  \(S\) does not appear to be strictly diagonally dominant

• -16

  ill-conditioning has prevented furthr progress

Int32 alloc_status

STAT value after allocate failure.

Int32 factorizations

the number of factorizations performed

Int32 len_history

the number of (\(\|x\|_S\), \(\lambda\)) pairs in the history

T r_norm

corresponding value of the two-norm of the residual, \(\|A x(\lambda) - b\|\)

T x_norm

the S-norm of x, \(\|x\|_S\)

T multiplier

the Lagrange multiplier corresponding to the trust-region constraint

NTuple{81,Cchar} bad_alloc

name of array which provoked an allocate failure

struct llst_time_type time
