WP 34S: a litlle matrix helper to enter and review matrices  Miguel Toro  10082011 Hi, Nothing fancy here, just a little routine to help entering and reviewing matrice for the WP 34s, based on the MIO application of the PPC ROM. Hope you find it useful and please, any comment to improve it, is very very welcome. Miguel

Re: WP 34S: a litlle matrix helper to enter and review matrices  Paul Dale  10082011 Marcus wrote a small matrix editor for the 34S. It is in the library directory on subversion at sourceforge. I've no idea how the two compare  I've used neither so far :)
Re: WP 34S: a litlle matrix helper to enter and review matrices  Marcus von Cube, Germany  10092011 Mine ('MED') doesn't allow the sequential input of all elements. You need to navigate there with the arrows, start typing, press R/S, then one of the arrows again to go to the next element. Entering a single element needs either arrow navigation or manually setting I and J as the indexes.
What I don't like with your routine, Miguel, is that you have to press the function key, then enter the matrix descriptor and then R/S. Why not just enter the descriptor and then press the function key?
Re: WP 34S: a litlle matrix helper to enter and review matrices  Miguel Toro  10092011 You are correct. I will make the changes in the routine and the article. Thank you Marcus.
Done! Edited: 9 Oct 2011, 7:54 a.m. after one or more responses were posted

Quote: If you look closely at these two, they are completely identical from the user's point of view. The only difference is that he has to enter a value and press R/S again if he wants to update the cell. So why not just ditch [D] and add a STO operation just after the last STOP in [C]? If the user just wants to see an element he does not enter any new data.
Quote:This can be replaced by [alpha]IP which appends only the integer part. You need to add a delimiter. Re: WP 34S: a litlle matrix helper to enter and review matrices  Miguel Toro  10092011 Great!!! I will do the changes. Thank you very much Marcus. Regards,
Miguel
Re: WP 34S: a litlle matrix helper to enter and review matrices  Miguel Toro  10092011 I made a major overhaul of the routine (Marcus von Cube being the culprit of that :) ). The routine is simpler for the user and easy on resources for the WP 34s. Thank you Marcus, Miguel

Quote:You get in trouble with a matrix starting in R00 or R01. Re: WP 34S: a litlle matrix helper to enter and review matrices  Miguel Toro  10092011 Yes, It intended to begin at R10 so there are some registers left to do other things. I will write a comment, so at least leave R0 and R1 free.
Re: WP 34S: a litlle matrix helper to enter and review matrices  fhub  10092011 Quote:Why don't you use register I instead of R1? Then you won't have any restrictions where the matrix is located. Re: WP 34S: a litlle matrix helper to enter and review matrices  Miguel Toro  10092011 Mince alors! I always forget about that. Certainly. I will change that. Thanks, Miguel Done!
