# constant_pwc_operator¶

Graph.constant_pwc_operator(duration, operator, *, name=None)

Creates a constant piecewise-constant operator over a specified duration.

Parameters
• duration (float) – The duration $$\tau$$ for the resulting piecewise-constant operator.

• operator (np.ndarray or Tensor) – The operator $$A$$, or a batch of operators. It must have at least two dimensions, and its last two dimensions must be equal.

• name (str, optional) – The name of the node.

Returns

The constant operator $$t\mapsto A$$ (for $$0\leq t\leq\tau$$) (or a batch of constant operators, if you provide a batch of operators).

Return type

Pwc

constant_stf_operator()
pwc_operator()
pwc_operator_hermitian_part()
