I use a FX-9750g PLUS and am trying to get the Reduced Row Echelon form of a Matrix. The Casio site says that the program to do this is already loaded into my calculator but it isnt. I do have the program text that you are supposed to create the program with, but its very confusing. Can anyone put this into simpler terms for me? I have never created a program before.

Hi, to get the RREF (reduced row echelon format) command in your calculator you must be in main mode. First press the OPTN' /> button. Then you must go into MAT. It should be F2' /> but may not be. Then try to find the RREF command.

Hope that this helps,

[mintsmike]

The RREF feature is probably not included in your calculator then,

Sorry I could not be of more help.

Only the models 9850GB PLUS and 9950GB PLUS have software library programs built-in.

For any other model the program must be typed in or transferred via cable, however the doc file given in the casioeducation link: http://www.casioeduc...A8-9088C88C19BF
needs to be viewed with the correct fonts.

I pasted the text from the rowreda.doc into the program Casform to find which font it is supposed to be (it turned out to be FA-121) and then converted it into plain text.

The plain text is:

"ROW REDUCE MATRIX A"
Dim Mat A
List Ans1->R
List Ans2 ->C
Mat A->Mat R
1->I
For 1->J To C
For 1->N To R-I
Mat R[I,J]=0=>Swap R,I,I+N
Next
If Mat R[I,J]<>0
Then *Row 1%Mat R[I,J],R,I
For 1->KTo R
K<>I=>*Row+ (-)Mat R[K,J],R,I,K
Next
Isz I
IfEnd
If I=R+1
Then Mat R[R,J]=1=>Break
Dsz I
IfEnd
Next
Mat R


(-) -the unitary negative sign
=> -implicaton symbol (if,then symbol)
-> -assignment arrow
<> -not equal to
% -represents the fraction symbol on the a b/c button

The location of the other commands is given in this table:

If this program doesn't work then there is another rowreda program in this topic:

Hi,

I dont see the other models, but Ref&Rref commands are Added on fx-9860GII.

I found this http://math.fullerto...lonFormMod.html

Ok, yes the new GII models have rref and the 9860 models can have an OS upgrade to include rref and the Algebra FX 2.0 Plus includes rref in its symbolic mode.

I was thinking about the old 9x50 series models. Only the GB versions of the old 9x50 series have rref built-in.

Thank you so much for this post!!! You have no idea how much you've helped. For anyone out there with a Casio fx-9750GA Plus, this works wonders~ However, I would like to make it easier for people who are new at coding (much like myself) on some things: When typing out the "List Ans" part make sure to put the 1->R and 2->C in a bracket. So it would look like: List Ans 1>R *The same applies for the second line * Also, on the "For 1->N To R-I" part, instead of a - between the R and I the proper symbol would be the fraction symbol. Following the key, it would be "For 1->N To R%I". For any other questions, follow caspro's first link! It provides a key input guide to get certain symbols! (This one: http://www.spiderpix...ml/9850key.html) That is all I believe, so good luck~!

Hello. I am new here, and I have this fx9750g plus, and I need some advice about rref. first at all what kind of cable would i need for this? and some instruction on how to insert this program into my calculator?

[pan.gejt]

You need FA-123 cable.

Concerning insertion, retype the program instructions to your calc.

The special characters and programming commands can be found after pressing shift+vars [prgm]
