Last, Dimension in CAS don't work properly
In CAS the commands Last, Dimension, Take (with Length) don't work properly.
In Algebra (entering in the Input Bar) they work!
In the attached file
you find some examples.
returns -> ? in CAS.
See CAS#2, #4, #6 in the attachment.
returns -> ? in CAS if Matrix has only 1 row.
See CAS#12, #16
Using Length to get the last row with Take
does not work/returns an error.
See CAS#7, #19
does return the row before last.
Calculating the length in advance
and then using it within Take works!
See CAS#7 - #10, #19 - #21
Typing Length in an empty CAS cell only offers
although they are accepted.
This seems to be a new feature in GeoGebra 5.0.47:
- To be able to open the context menu of an object in Graphics View (right-click) you MUST select the object first and then right-click on it?!
In GeoGebra 5.0.42 (4.4.40+) you can immediately perform the right-click on an object in Graphics to get the context menu without having to select the object beforehand.
