VectorSet ADFun< Base >::RevSparseJac | ( | size_t | p, |
const VectorSet & | s | ||
) |
User API for Jacobian sparsity patterns using reverse mode.
The C++ source code corresponding to this operation is
s = f.RevSparseJac(q, r)
Base | is the base type for this recording. |
VectorSet | is a simple vector with elements of type bool . or std::set<size_t> . |
p | is the number of rows in the matrix ![]() |
s | is a sparsity pattern for the matrix ![]() |
VectorSet::value_type
is bool
, the return value r
is a vector with size p*n
where n
is the number of independent variables corresponding to the operation sequence stored in f
. If VectorSet::value_type
is std::set<size_t>
, the return value r
is a vector of sets with size p
and with all its elements between zero and n
- 1. The value of r is the sparsity pattern for the matrix
