  • A matrix that has m rows and n columns is called a matrix of order m × n.
  • [aij]m×1 is a column matrix.
  • [aij]1×n is a row matrix.
  • An m × n matrix is a square matrix if m=n.
  • A = [aij]m×m is a diagonal matrix if aij=0, when i≠j.
  • A = [aij]n×n is a scalar matrix if aij=0, when i≠j, aij=k (k is some constant), when i=j.
  • A = [aij]n×n is an identity matrix if aij=1, when i=j, aij=0, when i≠j.
  • A zero matrix has all its elements as zero.
  • A = [aij] = [bij] = B if (i)A and B of the same order, (ii) aij = bij for all possible values of i and j.
  • kA = k[aij]m×n = [k(aij)m×n]
  • -A = (-1) A
  • A – B = A + (-1) B
  • A + B = B + A
  • (A + B) + C = A + (B + C), where A, B and C are of the same order.
  • k (A + B) = kA + kB, where A and B are of the same order, k is constant.
  • (k + l) A = kA + lA, where k and l are constant.
