Estoy haciendo un programa, para resolver ecuaciones lineales, al momento de codificar una 6x6, necesito muchas mas variables. Ejemplo: Utilizo A,B,C,D,E,F,J,H...W,X,Y,X. Necesito aun mas.

I don't believe so. You can also use r (ALPHA and x^2) and the 0 with a slash through it (idk what is is, ALPHA and ^)

You could try using a matrix to store data, I don't know how to. I'm not sure about this either but maybe use an array, though I don't think that is possible. Best bet is using a matrix.

 

Found this from the tutorial of the Casio basic on another post on this forum

 

////////////////////////////////////////////////////

Matrices – A matrix is a two dimensional list
Here is a visual of a 5x4 matrix.
[ ][ ][ ][ ]
[ ][ ][ ][ ]
[ ][ ][ ][ ]
[ ][ ][ ][ ]
[ ][ ][ ][ ]
Matrices are just like lists except that they are two dimensional, I like to use them for maps, especially tiled maps. To use a matrix use Mat (letter A~Z)[Y,X] (Mat A[1,1]), the X and Y are reversed, make sure not to confuse them.

You may split your program in parts. Every part has to be so small that A-Z are sufficient. To call a subroutine, use some kind of Push and Pop :

Push:

{A,B..Z} -> List 9 

 

Pop (I found no shorter form):

List 9 [ 1 ]->A

List 9 [ 2 ]->B

:

List 9 [ 26 ]->Z

 

Best store Push and Pop as Programs

Hi

 

With Push & Pop way of doing, Matrix is very little bit faster than List.
