    matrix representation of linear algebra

    I am stuck trying to figure out how to solve for a matrix A given the transformation T(v) and v.

    I have T(v) = Av and need to find A (a 2x2 matrix). Any ideas?

    post the question. if this is the kind of question i think you are asking, you just need to reverse matrix multiplication. which is easier than it sounds, since the numbers tend to be in their respective positions

    The question

    Ok so I have v = [.3355, .4792]^t and T(v) = [-.1747, .8478]^t and I am trying to find A (a 2x2 matrix), where T(v) = Av.
