◆ FillJacobianBlock()

void ifopt::ExCost::FillJacobianBlock	(	std::string	var_set,
		Jacobian &	jac_block
	)		const

inlineoverridevirtual

Set individual Jacobians corresponding to each decision variable set.

Parameters

var_set	Set of variables the current Jacobian block belongs to.
jac_block	Columns of the overall Jacobian affected by var_set.

A convenience function so the user does not have to worry about the ordering of variable sets. All that is required is that the user knows the internal ordering of variables in each individual set and provides the Jacobian of the constraints w.r.t. this set (starting at column 0). GetJacobian() then inserts these columns at the correct position in the overall Jacobian.

If the constraint doen't depend on a var_set, this function should simply do nothing.

Attention: jac_bock is a sparse matrix, and must always have the same sparsity pattern. Therefore, it's better not to build a dense matrix and call .sparseView(), because if some entries happen to be zero for some iteration, that changes the sparsity pattern. A more robust way is to directly set as follows (which can also be set =0.0 without erros): jac_block.coeffRef(1, 3) = ...

Implements ifopt::ConstraintSet.
