StreamSmart

Has anyone heard anything more about a version of StreamSmart compatible with the HP50g as well as the 39/40? Also has anyone heard anything about whether Vernier sensors will be usable with an adapter. I have had discussions with various member of my department about getting one to test out. However they are not willing to go beyond... more »

entry point EDITPARTS
|
| |
I dissembled this entry (see below) and cannot understand why there is a call to =firstchar that simply gets overwritten with the number of carriage returns upon reading from =EditParts. Can anyone explain this? (SNIB9 is a nibble that determines whether or not we are in edit mode.) ****************************** ****************************** *********... more »

|
| |
Hi Performing some matrix calculations in System RPL, I didn't find a big time difference as compared to User RPL. Can they somehow be made faster in SysRPL? I only deal with real matrices and of order atmost 10 X 10(rarely, usually around 4). The basic operations I use are /, *, +, -, inverse, transpose, etc. to do some stuff related to complete... more »

Few question about gradient/deriv and saving a vector function...

Lets say that I have defined some simple scalar function for example: DEFINE('P(X,Y,Z)=X^2+Y^2+Z^2') NOVAL Then I stored a simple vector: [X,Y,Z]|>J [X Y Z] If I want do calculate gradient of my scalar function the manual states: DERIV(X^2+Y^2+Z^2,[X,Y,Z]) [2X 2Y 2Z] If I use: DERIVE('P(X,Y,Z),[X,Y,Z]')... more »

ML decomp and Eqstk for HP48GX
|
| |
Hi everyone, I spent a few days searching comp.sys.hp48 for bugs relating to the ML decomp (which can be found in Java). Have all the ML decomp bugs been found and fixed (namely the one having to do with arrays)? I also managed to dig up an old post on Java being somewhat slower in displaying algebraic objects than Eqstk even though it is the same... more »

replacing an HP16C with the HP50G
|
| |
Hello, I would like to use my 50G to replace my 16C, but the standard functions do not provide the ALU flags. Do you know about a library which would fill the gap at UserRPL level ? Thanks, Patrice

Does anyone know have such a card? I am aware that SMI and TDS make such cards. What is the expected lifespan of such cards?
