I'm reading about the lattice recently.In the paper, it gives a method of a vector mod a matrix:
⃗c mod B as ⃗c−⌊⃗c×B^(−1)⌉×B = [⃗c×B^(−1)]×B.
I know that a integer A mod the other integer B is A+-kB, to make A in the defined field B.
Can anyone tell me what is the meaning of a vector mod a matrix and the mid term ⌊⃗c×B^(−1)⌉ means?:(
