Return value if not None; otherwise evaluate compute_expression_from_coordinates.

This is a convenience wrapper for evaluating on 1D coordinate arrays with optional fixed axes.

Parameters:

  • value (array-like or None) – Precomputed result or None to trigger evaluation.

  • expression (str) – The name of the expression to evaluate if value is None.

  • coordinates (list of array-like) – 1D arrays for each free coordinate axis.

  • fixed_axes (dict of {str: float}, optional) – Fixed scalar coordinate values.

  • sparse (bool, optional) – Whether to construct sparse coordinate arrays.

Returns:

Either the provided value or the computed result.

Return type:

array-like
