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!
