MatMFFD#
A data structured used to manage the computation of the h differencing parameter for matrix-free Jacobian vector products
Synopsis#
typedef struct _p_MatMFFD *MatMFFD;
Notes#
MATMFFD is a specific MatType which uses the MatMFFD data structure
MatMFFD*() methods actually take the Mat as their first argument. Not a MatMFFD data structure
This functionality is often obtained using MatCreateSNESMF() or with SNES solvers using -snes_mf or -snes_mf_operator
