Question

What is the best or the easiest way to invert a matrix?

Answer 1

gaussian elimination the best and almost all the time the easiest.

the worst (computationally) is the cramer rule, using the cofactors.

Answer 2

Thank you very much.

Answer 3

actually if you perform a gauss elimination you need to remember a lot of steps in your head and then rearrange the rows accordingly. so you end writing both equations and matrices for your steps. i think the cofactor is easy in the sense that you write it step by step and and you can easily figure out in case you went wrong somewhere.

Answer 4

for me the easiest to invert matrix you mast be count the colume and the row
