Class FirstOrderLinearTIR¶

Defined in Program listing for file kernel/src/modelingTools/FirstOrderLinearTIR.hpp

class FirstOrderLinearTIR : public FirstOrderR ¶

Linear Time Invariant Relation, derived from class FirstOrderR.

Linear Relation for First Order Dynamical Systems with time-independant operators

\[\begin{split} y &=& Cx(t) + Fz + D\lambda + e \\ R &=& B\lambda \end{split}\]
