quiver(X,Y,U,V) plots vector field with cartesian coordinaes (U,V) defined on a parametric or non parametric mesh defined by (X,Y) (see e.g. surf for a discussion about the relative sizes of X and Y). The vectors are automatically scaled to fit in the grid defined by X and Y.
The last argument 'fact' is a scale factor for the vectors, if you want to change the length of vectors. If you don't want any scaling at all, use fact=0.
