transform_ddts()

TransformerTemplate.transform_ddts(ddts, inplace=False)

Apply the learned transformation to snapshot time derivatives.

If the transformation is denoted by \(\mathcal{T}(q)\), this function implements \(\mathcal{T}'\) such that \(\mathcal{T}'(\ddt q) = \ddt \mathcal{T}(q)\).

Parameters:

ddts(n, …) ndarray

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

inplacebool

If True, overwrite ddts during the transformation. If False, create a copy of the data to transform.

Returns:

ddts_transformed(n, …) ndarray

Transformed n-dimensional snapshot time derivatives.
