What does this notation mean?
Hi, I'm working through a Linear Algebra textbook and I've run into a notation that I can't seem to find explained in the textbook. At least, I think it's a notation?
Basically, I was given two arrays like:
........2 0 3
A =..4 2 3
........5 3 2
........5 0 4
B = ..7 3 3
........2 3 1
(numbers are made up, if it matters I can dig up the actual numbers)
The first things I had to do with this was figure out 2A - 2B, this was all well and good.
The second thing I had to do was figure out . There is the issue, I'm not sure what this T is, I don't see any value assigned to T in the question and I can't find an explanation of what to do with T in the textbook.
Does anyone know what this means? Thanks!
