Is there another MATLAB command like fill. If I utilize this command the output is not what I'm looking for. I want the area inside these coordinates value.
fill(coord_x, coord_y, 'r')
The code connects the points not in the way I want. Is there any other command?

Maybe your coordinates are not correct. Look at this example
fill([0 1 1 0 0],[0 0 1 1 0],'r')
xlim([-2 2])

Francesco, thanks for your remarks, but accepting an answer means your problem is solved, you can vote an answer, but don't accept it until it helps you,
Try this
coord_x =[ 32.5000 32.5000 37.0000 37.5000]
coord_y =[17.5000 13.7500 16.0000 15.0000]
[idx,idx]=sort(coord_y)
fill(coord_x(idx), coord_y(idx), 'r')

Find the centroid of the points. Then sort all of the points according to their polar angle relative to the centroid. If you sortrows() of the angle and the radius and then you reverse the order then it will be counter-clockwise and largest radius first, which happens to be one of the better ways of creating polygons.
