Scale `polyshape`

`polyout = scale(`

returns a `polyin`

,`s`

)`polyshape`

object defined by scaling
`polyin`

by a factor `s`

with respect to the
reference point (0,0). If `s`

is a scalar, then
`scale`

applies it to both the *x* and
*y* directions. If `s`

is a two-element row
vector, then the first element is the scale factor in the *x*
direction and the second element is the scale factor in the *y*
direction.
