    MODATA_LASTMAT doesn't give you the previous matrix

    I just ran into this as well. It seems very odd to me, because the documentation says it should.

    MODATA_LASTMAT     Matrix     Previous frame particle matrix.

    Yet, this is what I get when I print each of these matrices:

      
    ---   
    Frame 1   
    Current: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 4.67, -211.111))   
    Last: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (0, 0, 0))   
    Start: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 0, -211.111))   
      
    ---   
    Frame 2   
    Current: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 4.377, -211.111))   
    Last: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (0, 0, 0))   
    Start: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 0, -211.111))   
      
    ---   
    Frame 3   
    Current: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 4.039, -211.111))   
    Last: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (0, 0, 0))   
    Start: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 0, -211.111))   
      
    ---   
    Frame 4   
    Current: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 3.709, -211.111))   
    Last: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (0, 0, 0))   
    Start: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 0, -211.111))   
      
    ---   
    Frame 5   
    Current: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 3.433, -211.111))   
    Last: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (0, 0, 0))   
    Start: Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (-211.111, 0, -211.111))

    Hi Donovan,

    sorry, it took so long. I needed reassurance from development side.
    We need to fix our documentation. MODATA_LASTMAT is for internal usage, only.
    Douwe's approach is still your best bet.
