web.mit.eduDefinition. Addition of two matrices A and B, both with dimension m by n, is defined as a new matrix C, written C = A + B, whose elements cij are given by cij = aij +bij. For example, 1 2 4 0 −3 1 + 2 6 −3 −1 4 0 = 3 8 1 −1 1 1 (A) (B) (C) If two matrices A and B do not have the same dimension, then A + B …
