finesse.densematrix.DenseMatrix.add_submatrix

DenseMatrix.add_submatrix(_from, _to, name, callback=None, type_='m')

Adds a submatrix to the matrix. The nomenclature of _from and _to refer to the variable dependency of the equations this submatrix represents, i.e. the equations in submatrix _to depends on the values in -from. Therefore _from is the subcolumn index and _to is the subrow index.

Parameters

_from : long

Subcolumn index

_to : long

Subcolumn index

name : unicode

Name used to indentify this coupling in the matrix for debugging

callback : function()

A callback function that will be called once the matrix has been constructed

type_ : char (optional)

Either ‘m’ for a full submatrix or ‘d’ for a diagonal element only submatrix
