Detailed Description

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

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

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 maxInEq() const override; number of inequality lines
• std::string nameInEq() const override; descriptive name of the constraint
• const Eigen::VectorXd & bInEq() const override; returns \(b\)
