How to calculate the coordinates of the overlaped points over a polygon?

The example on which i tried to apply the inpolygon is:

solux=[5.95,6.40,6.2,6.3,6.42,6.81,7.26,7.76,6.5,8.1,8.17,8.6,9.06,9.5,8.1]

and soluy = [37.5,37.3,36.8,36.3,35.8,35.5,35.3,35.3,35.1,35.02,34.5,35.07,34.7,34.7,34.02];

and the coodinates of polygon is attached in the attachment. I have used the 'inpolygon(solux,soluy,xv,yv)' to solve the problem, but im unable to draw the coordinates of the polygon into 'xv' and 'xy'. Please find the files for coordinates of the polygon in 'trialdataofcoordinates.mat' file. Please help me out.
