transform_ddts()

ScaleTransformer.transform_ddts(ddts, inplace=False)

Apply the scaling; the transformation for derivatives is the same as for snapshots.

Parameters:

ddts(n, …) ndarray

Matrix of n-dimensional snapshot time derivatives, or a single snapshot time derivative.

inplacebool

If True, modify ddts inplace. If False (default), return a new array.

Returns:

ddts_scaled(n, …) ndarray

Scaled snapshot time derivatives.

Raises:

AttributeError

If scaler is a number (not an array) but fit() or fit_transform() have not been called yet.

ValueError

If the ddts do not align with the state_dimension.
