fronts.do_dt

fronts.do_dt(r, t)

Time derivative of the Boltzmann transformation.

Returns the partial derivative \(\partial o/\partial t\) evaluated at (r, t).

Parameters:
  • r (float or numpy.ndarray) – Location(s). If an array, it must have a shape broadcastable with t.

  • t (float or numpy.ndarray) – Time(s). If an array, it must have a shape broadcastable with r. Values must be positive.

Returns:

do_dt – The return is a float if both r and t are floats. Otherwise it is an array of the shape that results from broadcasting r and t.

Return type:

float or numpy.ndarray
