xfpolys — fill a set of polygons
xfpolys(xpols,ypols,[fill])
| xpols,ypols | : matrices of the same size (p,n) (points of the polygons). |
| fill | : vector of size n. |
xfpolys fills a set of polygons of the same size defined by the two matrices xpols and ypols. The coordinates of each polygon are stored in a column of xpols and ypols.
The pattern for filling polygon number i is given by fill(i):
| - | if fill(i)<0, the polygon is filled with pattern id -fill(i). |
| - | if fill(i)=0, the polygon is drawn with the current dash style (or current color). |
| - | if fill(i)>0, the polygon is filled with pattern id fill(i). Then its contour is drawn with the current dash (or color) and closed if necessary. |
