Coupling matrix window:

	Read matrix from disk.
	Save current matrix to disk.
	Store current matrix in list.
	Remove matrix from list.
	Plot [S] parameters and check error with Characteristic Polynomials.
	Plot stored energy and dissipated power.
	Edit current coupling matrix.

There is a coupling matrix list where you can store, load or delete matrices. Loading a matrix from the list updates the coupling matrix and Q table entries. There is also a matrix editor to manually edit matrix entries and to perform matrix rotations.

Matrix Editor Window

The matrix editor has a list of edit actions. Actions can be undone. Double-clicking an action in the edit actions list loads the coupling matrix state after that action was done.

Error in [S] parameters after Coupling Matrix rotations

To assess the roundoff error in matrix rotations, it is possible to compare [S] parameters computed from current coupling matrix with [S] parameters computed from characteristic polynomials. The average error is shown at the bottom of the window.
