dq.modulated

modulated(f: callable[[float, ...], Array], array: ArrayLike) -> ModulatedTimeArray

Instantiate a modulated time-array.

A modulated time-array is defined by \(O(t) = f(t) O_0\) where \(f(t)\) is a time-dependent scalar. The function \(f\) is defined by passing a Python function with signature f(t: float) -> Array that returns an array of shape (...) for any time \(t\).

Parameters

• f (function returning array of shape (...)) –

  Function with signature f(t: float) -> Array that returns the modulating factor \(f(t)\).

• array (array_like of shape (n, n)) –

  Constant array \(O_0\).

Returns

(time-array object of shape (..., n, n) when called) Callable object returning \(O(t)\) for any time \(t\).
