Write a summary of supported operator expressions about odl HOT 11 CLOSED

Sure we can do this, but this is already documented (or should be) in the functions __add__, __mul__ etc, shouldnt this be enough?

from odl.

Yes, sure, but I was more thinking of a chapter in the introduction. IMO it is one of the strengths of ODL and it should not be hidden in the API doc.

from odl.

Sure why not. In that case I'd simply do the first three points however. The last one is a "implementation detail" imo.

from odl.

Right. But we could link to the place in the API doc.

from odl.

Yes indeed! Simply writing:

(scalar * A)(x) = scalar * A(x)
(A * scalar)(x) = A(scalar * x)
(A * B)(x) = A(B(x))

etc would be enough imo. With good naming it will be clear that A is a operator and scalar is a "appropriate" scalar. Details such as conditions on scalar can be in the (linked to) api doc.

Regarding the API doc we need to add __add__ etc to the doc, see #18.

from odl.

Alright! I can take that one.

from odl.

Has this been done?

from odl.

No, just an intro to operators in general in the init file of the operator submodule. Rest is TODO.

from odl.

The intro has been moved to the doc, I'll add this summary there.

from odl.

This has been solved Operator Arithmetic

Looks good!
