    Given vectors find the matrix

    Hello everyone


    I have been given 4 seperate vectors: all vertical example
    v1 v2 v3 v4

    1 5 9 1
    2 6 8 2
    3 7 7 3
    4 8 6 4

    i have converted this into the matrix
    1 2 3 4
    5 6 7 8
    9 8 7 6
    1 2 3 4

    is this the correct way to convert into matrix form?

    It depends what you want to do with them next. You have transposed the columns into rows. Is there a particular reason why you did so?

    If these vectors are going to be transformed by multiplication on the left by a 4x4 matrix, you would leave them alone, without transposing.

    If you converting a system equations into a matrix and intend to multiply it by the vector w x y z then you are correct in the way you converted them.
