Matrices were used very often as codes during WWII. It was an excellent way to encode secret messages. Unless someone has the matrix with which to decode the other matrices it would be nearly impossible to uncode the message. Lucky for you, you have all the information you need to decode the message. Let's see if you can!

Your main matrix is:

[-3 -2]
[ 4 3]

Decode the message:

11, 12, -15, -10, -3, 0, 8, 6, -75, -50, -32, -21, -26, -16, 80, 60, -9, -1, 36, 27, -18, -12, 94, 71, 76, 57, -11, -7. - -44, -29, -15, -6, 72, 54, 73, 56, 57, 44, -15, -10.

I thought this was the Trick category, so when it said look at the title, I thought the answer was the title.
