Converts dimension units for the input space to dimension units for the output space.

Output dimensions with OutputIndexMethod::single_input_dimension maps are assigned the unit of the corresponding input dimension, if any, divided by the absolute value of the stride.

The units of output dimensions with OutputIndexMethod::constant and OutputIndexMethod::array maps are left unspecified.

If a unit is specified for an input dimension, but no output dimension depends on it via a OutputIndexMethod::single_input_dimension map, an error is returned to indicate that this unit would be “lost”.

Parameters:¶

IndexTransformView<> transform¶

Index transform.

DimensionUnitsVector input_units¶

Units for each input dimension of transform.

Error absl::StatusCode::kInvalidArgument:¶

if a unit is specified for an input dimension that does not correspond to an output dimension.
