If the object has position (x1, y2) at time t and (x2, y2) at time t+1, it moved in the direction (x2 - x1, y2 -y1).

In general you should start a new question if you have a new question. In this case I answer it anyway: Draw an arrow from P1 to P2, google it if you don't know how to draw arrows in Matlab; and the values you get could be positive or negative... That gives you some idea how to define a direction as positive or negative :-)
