Draw the velocity vectors and then the streamlines for this flow. Let

and

$.$

To do this, first define $[$x$,$y$]$ meshgrid.

To draw the velocity vector, use quiver $($x$,$ y$,$ u$,$ v$).$

The streamline uses streamline $($x$,$ y$,$ u$,$ v$,$ startx, starty$).$

Based on the direction of the velocity vector, the startx, and starty, use the beginning points.

The x is defined $[-1$:$0\mathrm{.}1$:$1],$ and the y is defined $[0$:$0\mathrm{.}1$:$1].$
