Texas Instrument Ti84+

Post by Anakin »

Hi,

on/at(?) my school we have the Ti84+ from Texas instrument.
you can program with it and i have much programs for school. now i have a problem.
i need Matrix. you all know?? something like this:
0 1 3 4 0
4 5 7 3 6
1 8 9 4 3

so how can i store inputs in a matrix??

i just started to learn app programing.
i downloaded the AXE app from the last link and i think it will work with this but i started today reading this and i'm not good in english.

some informations here:

So can someone read the tut from the 2nd url and can tell me if i can do this with the app and tell me if i'm right?? if not i needn't learn this.

or did someone know an other way to store inputs as matrix??

Press the 2ND button, and then press the x^-1 button, which will take you to MATRIX. Then use the right arrow button to go to EDIT. Press the ENTERbutton. Now choose from [A] to [J] to store your matrix. Upon selecting one of these letters, you will have the option to specify the dimension of your matrix. After doing this, you can then enter the elements of your matrix one by one. Upon entering your last element, press 2ND and MODE to quit. Now you can call upon your matrix by going to 2ND and then x^-1, and choosing the letter in which you stored your matrix under NAMES. Then if you want to take the determinant, transpose, or something else of your matrix, go to MATH for a list instead after pressing 2ND and then x^-1.
