Binary, Permutation, and Communication Matrices (VCE SSCE General Mathematics): Flashcards

Matrix containing only 0 and 1

Square matrix, one 1 per row/column, rest 0s

Rearrangement

Forming product $P imes X$ ($P$ comes first)

Forming product $X imes P$ ($P$ comes second)

$P^{-1} = P^T$ (inverse equals transpose)

Square binary matrix showing direct links in network

Square the communication matrix ($C^2$)

Links where sender and receiver are same person

$T = C + C^2$
