Hey, this is what I've got:
Plaintext:
To turn them into vectors in R3:
Turning them into numbers, then into a matrix:
Code:
7 4 11 11 14 19 7 0 17
Code:
[7 4 11]
[11 14 19]
[7 0 17]
Then we multiply by a matrix in R3 (the key):
Code:
[ 1 4 6 ]
[3 2 2]
[5 0 1]
And get a resulting 3x3 matrix, which can be re-written:
Code:
[74 36 61]
[148 72 113]
[92 28 59]
Code:
74 36 61 148 72 113 92 28 59
I'm wondering what kind of techniques to apply to solve this.
Thanks
Note: its hard to display matrices, I hope you guys get it.
