smagEvalObjGradProd
int smagEvalObjGradProd(smagHandle_t prob, double *x, double *d, double *f, double *df_d)
EXPERIMENTAL FUNCTION: Computes the directional derivative of the objective function.
smagSingleHessians
int smagSingleHessians(smagHandle_t prob, int *hesRowIdx, int *hesColIdx, double *hesValue, int hesSize, int *rowStart)
Gives the structure of the Hessian of the objective and each constraint separately.
