5. Equivalent matrices

5.1 Generalization of the equivalent system concept

An equivalent system is a single system grouping several elements, which operates with the same physical quantity as input and generates the same physical quantity as output.

As each element is represented by a matrix for linear models, the matrix product resulting from their grouping provides a single equivalent matrix with the same functionalities.

This notion of equivalent system is commonly used in other fields of physics, such as mirrors in electrostatics, or Thévenin and Norton's theorems in electrokinetics. In geometrical optics, and more specifically in paraxial optics, equivalent optical systems are defined in relation to particular...
