Hey guys, I was wondering if someone could give me a hand finding the inverse of a matrix Modulo 26. The matrix is as follows:
4 9 15
15 17 6
24 0 17
I am trying to get a 1 in the first slot, so I know that 4 can't go into 27 evenly to do that. I tried switching the first and the third row, then adding 1/5 of the second row to it to get 27 which = 1 mod 26, but this will get very messy very fast. Just wondering if this is the only way, or am I overlooking a more simplistic method?
