Hi,
 
I have a Casio FX-CG50 calculator. 
 
I'm doing matrix calculations and would like to input a matrix that has a variable in it, and when I evaluate the calculation to keep the variable.
For example:
 
x - variable
y - variable

Those are the matrices I want to enter, and that is the result I need to get. The problem is that I don't know haw to enter variables when defining a matrix and also if it's possible to do that and get a result in that form. 
 
I want to ask, is this possible? And if yes, how to do it.
If not, are there any addons or programs I can put on my calculator in order to achieve this?
 
Thanks in advance!

Sadly that's not possible, though you could make a program that evaluates the matrices for you.

You need a Classpad, or other calculator with CAS capabilities and matrix support under the CAS.

 

In the computer you can use SageMath, Xcas, Mathematica or other programs.
