I am trying to color the region 'A' in the figure using MATLAB. I have drawn the fours straightlines using the insert command button in the figure window of MATLAB.
I have seen fill , shade command but seems like they work when I give the explicit equations to the straightlines/ curves.
Any way to color the region A in the figure which is bounded by the four straightliunes.parallelogram.jpg

Try fill() or patch().


Still they need the equations of the lines, but yes it would be difficult to shade a region bounded by the curves whose equations are unknown, like just in case you want to do a free hand sketch / for example purposes. So how to proceed to color a region bounded by curves whose equations we donot know?
If you have vectors giving the x and y locations, then that's all you need.
