Matrix Editor Complex # NaN Problem
It appears that, with the new release, the matrix editor has problem with complex number entries and records NaN. For example, open up the matrix editor, try edit M1, enter 2+2*i, exit, and voila! ??????????????

Home and CAS, same problem.

Well dang...

Although I work for the HP calculator group, the views and opinions I post here are my own.

also here!
then, however, the matrix appear in CAS but not always with all the correct numbers: i.e. ok for [1,1+1i,1-i][2,2+2i,2-2i] but not for others...

Do you have an example where the numbers are not correctly stored?

For example if I have [[1+1*i, 2]] in M1, the editor displays NaN, but I can recall M1 to the command line OK. Of course, the user can't edit the NaN matrix any more - - if you attempt to do that, you get another row of NaN.

in this moment I can't reproduce that... I'll do other tries tomorrow.

However, I can edit "blindly" the NaN and the number (also complex) then appear in the command line...

This and that in Define are probably the most serious bugs after the FW update...

Well,

This happens. New update -> new bugs will be introduced.
