Detailed Description

Helper class to write an equality constraint for Tasks. This constraint applies to the vector of positive multipliers (lambda) associated with a given contact

This implements \( A * \lambda_{cI} = b \)

Where \(cI\) is the contact id you provide at construction.

You must implement the following functions:

  • const Eigen::MatrixXd & A() const override; returns \(A\), must be of size (nrLines, nrLambda)
  • void compute() override; update constraint matrix and bounds
  • int maxEq() const override; number of equality lines
  • std::string nameEq() const override; descriptive name of the constraint
  • const Eigen::VectorXd & bEq() const override; returns \(b\)
