# 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
