Matrix/Array 28/48/50 Question  Matt Agajanian  06042012 Hello all Can I dynamically access an array or matrix element by simply accessing it these ways: matrix/array name[var] or matrix/array name[row, col] Or am I only to use GET and PUT?

Re: Matrix/Array 28/48/50 Question  Oliver Unter Ecker  06042012 Sadly not. You'll need to use GET or GETI.
Re: Matrix/Array 28/48/50 Question  Matt Agajanian  06042012 Okay. Besides, that does follow the Postfix structure so, no matter. Just a thought.

And not a bad one either! I picked it up in RPL+ where you can use the array syntax you suggest. You also have a choice of 1based or 0based indices, and automatic support for circular arrays. (But RPL+ is not available on those HP calcs.)
Re: Matrix/Array 28/48/50 Question  KarlLudwig Butte  06042012 Hello Matt, I found the following process working for me:
'M(row,column)' EVAL @ to extract a matrix element Instead of EVAL in the first case you can use \>NUM, too. I've tried this on the HP49G, 49G+ and 50G. Hope this helps Regards

Re: Matrix/Array 28/48/50 Question  Gilles Carpentier  06042012 Hi I also use this and it works fine (49/50). Exemple to try :
{ 5 5 } RANM 'Mat' STO @ Create a 5x5 random matrix and store it
It also works with 'vector'

Re: Matrix/Array 28/48/50 Question  Oliver Unter Ecker  06042012 Apologies. I had forgotten about this option. Know though that it runs almost an order of magnitude slower! From another discussion elsewhere:

Re: Matrix/Array 28/48/50 Question  Matt Agajanian  06042012 Not certain which post to post this under. Thanks for all your brilliant methods to accomplish the functionality I needed.
Re: Matrix/Array 28/48/50 Question  Oliver Unter Ecker  06042012 So far, RPL+ is only implemented in one iPhone app: ND1 (ND0 is a free version to try out.) If you visit the forum, you can learn about what other devices are planned to be supported in the future.
If you know RPL and are just curious about what's new: RPL+ for RPL Users
