The Residuals class calculates and stores the quantities that appear on the right-hand side of the linear systems that arise at each interior-point iteration.

These residuals can be partitioned into two fundamental categories: the components arising from the linear equations in the KKT conditions, and the components arising from the complementarity conditions.
