lift_ddts()#

static LifterTemplate.lift_ddts(states, ddts)[source]#

Lift the native state time derivatives to the time derivatives of the learning variables.

Parameters
states(n, k) ndarray

Native state variables.

ddts(n, k) ndarray

Time derivatives of the native state variables. Each column ddts[:, j] corresponds to the state vector states[:, j].

Returns
ddts(n_new, k) ndarray

Time derivatives of the learning variables.
