HP Prime SIZE and OBJ> with matrices/vectors/lists  Printable Version + HP Forums (https://archived.hpcalc.org/museumforum) + Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum1.html) + Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum2.html) + Thread: HP Prime SIZE and OBJ> with matrices/vectors/lists (/thread251506.html) 
HP Prime SIZE and OBJ> with matrices/vectors/lists  Helge Gabert  09272013 Two questions: 1) I'm writing a program for the HP Prime where I would like to get the dimensions for an nxm matrix (user inputs the matrix). On the 50g, I can use SIZE and I'll get the dimensions as a list {n m}. On the Prime, I only get the row dimensions n. Any idea on how to get the column dimensions as well? Thanks.
2) Also, the 50G has the command OBJ>, spitting out all the elements (plus the dimensions) of matrices, vectors, or lists onto the stack. On the Prime, do I need to write a program to achieve this (basically, calling each element in a loop)? That's what I need SIZE for   see above. Thanks again!
Re: HP Prime SIZE and OBJ> with matrices/vectors/lists  iconmaster  09272013 1) Try rowDim and colDim.
2) The programming language does not work on a stack, so an OBJ> equivalent would be almost useless. Simply call each element in sequence.
Re: HP Prime SIZE and OBJ> with matrices/vectors/lists  Tim Wessman  09272013 1) SIZE on a matrix here seems to return { r, c } ??? 2) m1(r,c) for direct access/storage.

Re: HP Prime SIZE and OBJ> with matrices/vectors/lists  Helge Gabert  09272013 Yes, in home view you get {n m}, but not in CAS view (only n). This brings up an interesting question   if the user runs the program in home view vs. CAS view, are there possible inconsistencies to contend with?
Re: HP Prime SIZE and OBJ> with matrices/vectors/lists  Helge Gabert  09272013 Yes that works. Thanks for rowDim and colDim!

Re: HP Prime SIZE and OBJ> with matrices/vectors/lists  Helge Gabert  09272013 Thanks for the insight . . . that would explain it . . . but then you HAVE to be in home view for things to work properly, or not?
Re: HP Prime SIZE and OBJ> with matrices/vectors/lists  Tim Wessman  09272013 No, the programs created normally in the program catalog are numerical in nature. Thus any call to "size" will be the correct one  whether called from the CAS or anywhere else. CAS functions can be created, but currently only by manually creating them in the CAS environment. eg: myfunc(a,b,c):=begin a+b+c; end; [ENTER]
