Problem 52854. Poly2mask, drawpolygon or patch

Recently, I tried to plot a polygon in matlab, and I found there is a lot of embedded function that can be used. However, some functions will plot points at vertexes, it is really disgusting. Try to use different embedded functions given in the title and find their difference!
vertexes coordinates is given as follow:
x = [0 1 1 0];
y = [0 0 1 1];
Tips: patch is the answer!
