Creates a constant piecewise-constant operator over a specified duration.
duration (float) – The duration \(\tau\) for the resulting piecewise-constant
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.
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).
Corresponding operation for Stfs.
Create Pwc operators.
Hermitian part of a piecewise-constant operator.
