solve without user callbacks

stationarity errors: - for KKT conditions: with standard multipliers and current objective multiplier - for FJ conditions: with standard multipliers a

performs symmetric rank k update: C = alpha A A^T + beta C or C = alpha A^T A + beta C

performs back-solve with triangular A: op(A) X = alpha B or X op(A) = alpha B where op(A) = A or op(A) = A^T X is overwritten on B

add (infeasibility, objective) to the filter

column-wise lower triangular Lagrangian Hessian

whether the QP has a Hessian: determines BQPD's kmax (0 for an LP). Valid after a build().

LDL' (aka signed Cholesky) factorization without pivoting for symmetric indefinite matrices Returns true upon success (all pivots are larger in norm t

performs the matrix-vector operations y := alpha A x + beta y, or y := alpha A^T x + beta y,
