scipp.empty_like

scipp.empty_like(obj, /)

Return a new object with the same dims, shape, unit, and dtype as the input and all elements uninitialized.

If the input has variances, all variances in the output exist but are uninitialized. If the input is a DataArray, coordinates and attributes are shallow-copied and masks are deep-copied.

Warning

Reading from any elements before writing to them produces undefined results.

Parameters:

obj (scipp.Variable | scipp.DataArray) – Input object defining dims, shape, unit, and dtype of the output

Returns:

Same type as input – New object with uninitialized values and maybe variances.
