scipp.spatial.scalings_from_vectors#

scipp.spatial.scalings_from_vectors(*, dims, values)#

Creates scaling transformations from corresponding to the provided 3-vectors.

Parameters:

  • dims (Sequence[str]) – The dimensions of the variable.

  • values (ndarray[tuple[Any, ...], dtype[TypeVar(_Float, bound= float64 | float32, covariant=True)]] | Sequence[Any]) – A list or NumPy array of 3-vectors, each corresponding to scaling coefficients in the x, y and z directions respectively.

Returns:

Variable – An array variable of dtype linear_transform3.

Create a single scaling transformation.

Examples

Create multiple scaling transformations:

>>> import scipp as sc
>>> scales = sc.spatial.scalings_from_vectors(
...     dims=['scale'],
...     values=[[1, 1, 1], [2, 2, 2], [0.5, 0.5, 0.5]]
... )
>>> scales
<scipp.Variable> (scale: 3)  linear_transform3  [dimensionless]  [(...), (...), (...)]
