sparse_pwc_operator

Graph.sparse_pwc_operator(signal, operator)

Creates a sparse piecewise-constant operator (sparse-matrix-valued function of time).

Each of the piecewise-constant segments (time periods) is a scalar multiple of the operator.

Parameters

• signal (Pwc) – The scalar-valued piecewise-constant function of time \(a(t)\).

• operator (numpy.ndarray or scipy.sparse.coo_matrix) – The sparse operator \(A\) to be scaled over time. If you pass a NumPy array then it will be internally converted into a sparse array.

Returns

The piecewise-constant sparse operator \(a(t)A\).

Return type

SparsePwc
