Hi all i need a little help with Jordan form

  1. Oct 17, 2007 #1
    ok this is my problem...
    i have diagonalized the A matrix with the equation P^-1*A*P
    and the result is J=[-1 0 0;0 2 1; 0 0 2]. in order to find the e^Jt do i need to do the following? =>


    [-e^t t*e^t 1/2*t^2 *e^t

    0 2*e^t t*e^t

    0 0 2*e^t]


    I am not sure about the 2 and 3 elements in the first row of the matrix since i have zeros at the J matrix but a mathematics book confused me..

    Thanks in advance..

    i did a mistake this is the matrix..

    [e^-t t*e^t 1/2*t^2 *e^t

    0 e^2t t*e^t

    0 0 e^2t ]
