octave:2> B = rand (3, 2);                      (Create matrix 3 rows 2 columns, random vars, no printout)
octave:3> B     (Display B)

octave:4> 2 * A     (Matrix A times scalar a)
octave:5> A * B     (Matrix matrix multiply)
octave:6> A' * A    (transpose (A) * A)

octave:7> A \ b     (solve Ax = b)
