spectrochempy.full_like

full_like(dataset, fill_value=0.0, dtype=None, **kwargs)[source]

Return a NDDataset of fill_value.

The returned NDDataset have the same shape and type as a given array. Units, coordset, … can be added in kwargs

Parameters:

  • dataset (NDDataset or array-like) – Object from which to copy the array structure.

  • fill_value (scalar) – Fill value.

  • dtype (data-type, optional) – Overrides the data type of the result.

  • **kwargs – Optional keyword parameters (see Other Parameters).

Returns:

fulllike – Array of fill_value with the same shape and type as dataset .

Other Parameters:

  • units (str or ur instance) – Units of the returned object. If not provided, try to copy from the input object.

  • coordset (list or Coordset object) – Coordinates for the returned object. If not provided, try to copy from the input object.
