I have a realization relationship between a Business Requirement and Use Case. 
 
Each Use Case may have one or more extending or related Use Cases (i.e. includes or extends).
Question:  Is there a way to show the included/extended use cases within the RTM or report the connected relationships?

The Use-case may have zero or more other including/extending use-case.  These appear in the Traceability window; however, they don't appear in the Traceability Matrix... I was hoping that during the past 10 years this would come. But I can't find a way to do it.

This matrix lists direct links and no indirection. The User is bound to the Traceability window for that.

If it's not a bug, it certainly looks like an omission. Extend and Include are represented internally in EA as subtypes of the connector type 'UseCase'. 'UseCase' appears in the relationship matrix, but that isn't very useful if you can't distinguish Extends and Includes.

Thanks.

Based on my question to the forum and comments received by "qwerty" and "KP".

The traceability matrix (I assume you mean relationship matrix)  is a two dimensional thing. It shows if elements in the row are somehow direct connected to elements in the column.
I use that matrix either to find out direct connections or to create or delete direct connects.

Elements in the row might be connected somehow to a chain of element to other elements and the same could happen to elements in the columns.

If the matrix would show that indirect connections as well, using the matrix to connect/disconnect things would not work. Further on the benefit of the information that an element is connected to another somehow over maybe 1000 elements hops, I would put under question marks.
I understand that in you special use case such a feature could help. But it is special and not general.
EA provides the feature you are looking for, the traceability view, however on element by element basis.
