    Matrix problem

    [1]
    [7] [2 -1 5]
    [3]


    The first is a 3x 1 matrix and the 2nd is a 1 x 3. How do I multiply them?

    The same way you would multiply any matrices. The result is a 3 x 3 matrix. The first row is 1 * 2, 1 * (-1) and 1 * 5. The second row is 7 * 2, 7 * (-1) and 7 * 5, and so on.
