Create a constant operator multiplied by a sampleable signal.
signal (Stf) – A sampleable function representing the signal \(a(t)\)
or a batch of sampleable functions.
operator (np.ndarray or Tensor) – The operator \(A\). It must have two equal dimensions.
The sampleable operator \(a(t)A\) (or batch of sampleable operators, if
you provide a batch of signals).
Create a constant Stf operator.
Corresponding operation for Pwcs.
Sum multiple Stfs.
For more information on Stf nodes see the Working with time-dependent functions in
Boulder Opal topic.
