Hello good day.
I have the following matrix
A = [1 1 1 1
         2 2 2 2
         3 3 3 3];
What instruction or how do I add two more lines
equal to the third line, that is, it looks like this
A = [1 1 1 1
         2 2 2 2
         3 3 3 3
         3 3 3 3
         3 3 3 3];
Waiting for your valuable help
Regards
