DerivativesConstXpr Class Reference

Detailed Description

The return type for AutoDiff::derivatives() when the AutoDiff is const.

The underlying type is similar to an Eigen::Map<const Eigen::VectorXd> which includes all of the usual functions for element access and arithmetic.

(Advanced) To be more specific, because we need to scale up the Map by a constant, the underlying type actually goes something like this: Eigen::CwiseBinaryOp< Eigen::scalar_product_op, const Eigen::CwiseNullaryOp<Eigen::scalar_constant_op>(coeff), const Eigen::Map(data, size)>>
