linop.Real

class bartorch.linop.Real

Bases: LinearOperator

The real part, BART’s linop_zreal.

Real only in value: the result is still complex, with zero imaginary part, because that is the one kind of array BART’s operators pass between them.

Like Conj this is linear over the reals and not over the complex numbers, so it is self-adjoint for a real inner product and fails a complex dot test on its own. Composed between operators that are complex-linear it behaves like any other term; alone it is a projection, which is its purpose here.

Parameters:

shape (tuple of int) – The shape it maps to itself, C order.

Also has the methods and properties of LinearOperator.
