Hi,
How can I store and recall a matrix resulting from my calculation for later use? I know that the last result is stored as MAT Ans, but that will change once I do some other operations/calculTions. Therefore I would like to store the result in memory somehow for recall later when needed. Would appreciate your kind help.

If you already know Mat Ans, you should also know Mat A~Z. The assignment arrow ( ) works with matrices as well, so do this:

Mat Ans->Mat A

Any letter in place of A will do, of course.

Or just assign the result directly to a matrix instead of letting it go into Mat Ans (unfortunately somme commands don't support that, most notably those for recalling the cofficients or results of the simultaneous / polynomial equation solvers).

Hi!
Thanks. that works super. just have the calc for 2 days so still discovering function. may I ask more questions?
1. I tried to use the arrow to save also "normal" numbers (ans->1), but didnt work. What command am I missing? And how can I recall the info later?
2. I dont suppose the calc also do Cofactor Matrix?

Still practicing using the calc so still finding out what I dont know. Sorry that the questions come in piece meals. 😉

Thanks for the help.

Numbers aren't valid variables – letters are. You can do things like Ans→A and 12.5→X, and then recall the value by typing that letter.
