Matrix

Matrix class

Main Matrix Class.

class diffupy.matrix.Matrix(mat=None, rows_labels=None, cols_labels=None, graph=None, quadratic=False, name='', init_value=None)

Matrix class.

Initialize matrix.

Parameters

• mat – matrix initialization

• rows_labels –

• cols_labels – column labels

• graph – graph

• quadratic – quadratic

• name – name

• init_value – value to be initialized (int) or list of values from labels

validate_labels()

Sanity function to check the dimensionality of the Matrix.

update_ix_mappings()

Update the index-label mapping.

validate_labels_and_update_ix_mappings()

Update function, called when the Matrix mutates, combining the two previous functionalities.
