nlop.SumOfSquares

class bartorch.nlop.SumOfSquares

Bases: NonlinearOperator

Sum of squared magnitudes along axes, BART’s zss.

The reduced axes are kept with size one; the result is complex with zero imaginary part.

Parameters:

• shape (tuple of int) – Domain, C order.

• axes (sequence of int) – Axes summed over.

Also has the methods and properties of NonlinearOperator.
