Set Atomic Function Options

Syntax
afun.option(option_value) These settings do not apply to individual afun calls, but rather all subsequent uses of the corresponding atomic operation in an ADFun object.

atomic_sparsity
Note that, if you use optimize , these sparsity patterns are used to determine the dependency relationship between argument and result variables.

pack_sparsity_enum
If option_value is atomic_base<Base>::pack_sparsity_enum , then the type used by afun for sparsity patterns , (after the option is set) will be       typedef CppAD::vectorBool atomic_sparsity  If r is a sparsity pattern for a matrix $R \in B^{p \times q}$: r.size() == p * q .

bool_sparsity_enum
If option_value is atomic_base<Base>::bool_sparsity_enum , then the type used by afun for sparsity patterns , (after the option is set) will be       typedef CppAD::vector<bool> atomic_sparsity  If r is a sparsity pattern for a matrix $R \in B^{p \times q}$: r.size() == p * q .

set_sparsity_enum
If option_value is atomic_base<Base>::set_sparsity_enum , then the type used by afun for sparsity patterns , (after the option is set) will be       typedef CppAD::vector< std::set<size_t> > atomic_sparsity  If r is a sparsity pattern for a matrix $R \in B^{p \times q}$: r.size() == p , and for $i = 0 , \ldots , p-1$, the elements of r[i] are between zero and $q-1$ inclusive.
