Your program works for me and does exactly that.
With M1 being [[1,−3],[−1,1],[2,−2]], after executing function1 I get for A1: [[2,−6],[−2,2],[4,−4]] and for A2: [[0,0],[0,0],[0,0]]

However one thing that can explain that you have 0 for A1 and for A2 is if you have the spreadsheet app active, in this case when you type A1 or A2 on the command line you're referring to the A1 and A2 cells of the spreadsheet, not to your global variables which should anyway be available in the Matrix editor.

Thank you, I've tested on a calculator and it works.
What is your view, how would you solve this program.
Is there any trick to print Matrices in Terminal an them staying the same style like when we view them in home screen?
Would like to label to each one, so I dont have to write on paper A1 - Standard deviation matrix... etc...
