WebDec 8, 2016 · First we need to introduce yes another vector operation called the Outer product. (As opposed to the Inner product (dot product)). Let u be an m by 1 column vector and v be an n by 1 column vector. Then Outer (u, v) := u * Transpose (v), yielding an m by n matrix where the (i, j) element equals u_i * v_j. i\u0026e technician jobs in louisiana
