    If you’re simply trying to draw one large filled polygon around your entire set of scattered points, you can use the function CONVHULL to find the convex hull containing your points and the function PATCH to display the convex hull:

    x = rand(1,20);              %# 20 random x values
y = rand(1,20);              %# 20 random y values
hullPoints = convhull(x,y);  %# Find the points defining the convex hull
patch(x(hullPoints),y(hullPoints),'r');  %# Plot the convex hull in red
hold on;                     %# Add to the existing plot
scatter(x,y);                %# Plot your scattered points (for comparison)

    And here’s the resulting figure:
