int DAAppSetElementHessianRoutine(TAO_APPLICATION daapplication, int (*hess)(int[2],PetscScalar[4],PetscScalar[4][4],void*), int flops, void *ctx)Collective on TAO_APPLICATION
daapp | - the TAO_APPLICATION solver context | |
hess | - local function gradient routine | |
flops | - the number of flops done performed in the hess routine | |
fgctx | - [optional] user-defined context for private data for the evaluation. |
int hess(int coordinates[2], PetscScalar x[4], PetscScalar h[4][4], void* ctx)
coord | - the global coordinates [i j] in each direction of the DA | |
x | - the variables on the DA ( da[j][i], da[j][j+1], da[j+1][i], da[j+1][i+1] ) (bottom left, bottom right, top left, top right) | |
h | - the hessian of this local function for with respect to each variable | |
