The elementwise difference in an array is useful for regularization of noise in a timeseries, e.g. based enforcing smoothness based upon curvature: https://www.continuummechanics.org/beambending.html. Adding gradient for ndim > 1 helps when working with multiple time series simultaneously, such as during signal analysis.
