UnsplitRescale.forward(y: tensor) → tensor

Unsplit and rescale measurements

\[m = \frac{y_+ - y_-}{\alpha},\]

where \(y_-\) \(y_+\) are the raw measurements and \(\alpha\) represents their intensity.

Args:

y (torch.tensor): Raw measurements of shape \((*, 2M)\)

Returns:

torch.tensor: Rescaled and unsplit measurements of shape \((*, M)\).
