graphics - How can I change the edge line color when using the 'fill' function in MATLAB? -

I am writing code in which I want to plot MATLAB's fill command to 2D size To use. I can specify the fill color of the size, however, the border line color is always black. I should be like the colors of the border line color. How can I specify the border color?

see:

  Do H = Fill ([- 1 -1 1], [- 1 1-1 -1], 'W'); Axis ([-2 2 -2 2]); Set (h, 'edgecolor', 'white');  

should take care of the boundary.
