Let me first point out that I have not a clue how to program anything complex on the TI-84, but I would like to learn. I have created a few simple programs like Inflation and Pert, but those were easy to do as I just stored the variables and ran them through the formula.
I am trying to create a program for finite math, so I do not have to remember all of the formulas.
I would like to be able to prompt for the matrix size, then store the values of each row/column.
Then perform what ever function, rref, identity, etc.
For example a simple economy program using a 3x3 matrix
PROMPT for matrix size
PROMPT for matrix values
PROMPT for matrix square
PROMPT for Demand matrix size
PROMPT for Demand matrix values
Store the variables
Calculate the variables in the ((ident(3)-[A]^-1)*[D]
I use matrix A and D above just as examples, but they could be anything.
Sorry for the noob question, I am just wanting to learn how to program this.
Thank you.
