      Description

      Even without the scaling by the length and dt , when changing the speed the
      first point of the history is different.

      A possible cause of this is that the random numbers aren't being
      distributed along the time dimension last, and so altering the array length is
      altering which numbers from the random sequence end up in the first time
      slice of the history array.

      A solution would be to permute the array to the dimension that is dealt to
      last in the handing out of the numbers of the random sequence, which would
      presumably be first (the current position) or last dimension, then permute it
      back once the noise array is populated.
