  1. 49G/49G+/50G BUG - SIGMA Funtion

    Hi all, I found other 49G/49G+/50G bug:

    I have the array:

    MTR =
    [[ 1 2 3 ]
    [ 4 5 6 ]
    [ 7 8 9 ]]

    I need to solve: 'SIGMA(m=1,3,SIGMA(n=m,3,MTR(m,n)))'

    49G/49G+/50G Retunrs: 'MTR(m,1.)+(MTR(m,2.)+MTR(m,3.))+(MTR(m,
    2.)+MTR(m,3.))+MTR(m,3.)'

    the 48G/GX returns: 26 = (1+2+3)+(5+6)+(9)

    Try it!

    Hi all,

    Hi John H Meyers you are right, the SIGMA bug was found two years ago.

    I am re-writting a User-RPL manual and I will have to change my
    example about the double SIGMA funtion, for now.

    Hello,

    Now where do we get ROM #2.10 ?

    The support site from HP still shows the ROM upgrade from August,
    11th, 2006.

    Best wishes,

    Here is the response I got:
    "Thank you for contacting Hewlett-Packard.
    This is in response to your e-mail regarding the HP 50g Graphing
    Calculator.
    To my knowledge 2.10 has not been released. Unfortunately posting the
    code for the 50g rom update is beyond my support boundaries.
    Sincerely,
    HP Email Support"

    A petition perhaps? Looks like JYA will have to get involved somehow.
    Just noticed the smiley face; sarcasm??

    Thanks, Arthur

    Great!

    When's 2.11 coming?

    Will it have BP's next version of Geometry and spreadsheet?

    Will it give HP an "Edge"?

    I viewed your Hydrix video -- keep your mind on the road!

    Best wishes.

    As if HP cares about what I'm saying now.

    2.10 has been released and passed all regression tests over 2 years ago now
    There's no reason for them not to release it
