Some times your data comes out of Matlab like:

simout1.data(1:5)

ans(:,:,1) =

     0


ans(:,:,2) =

    0.3816


ans(:,:,3) =

    0.7054

Just give it a squeeze to bbring the data back to a single dimension.

squeeze(simout1.data(1:5))

ans =

         0
    0.3816
    0.7054
    0.9225
    1.0000
