How to crop a shapefile with a polyon?

Is it possible to crop a shapefile with a polygon (potentially a circle) using Matlab. I have the coordinates of buildings in a shapefile (and in xlsx file as well), and would like to extract the buildings within a given circle. Is that possible with Matlab?

Read about inpolyon.

S = shaperead('my shape file') ;
S = [[S(:).X]' [S(:).Y]'] ;

idx = inpolygon(S(:,1),S(:,2),xc,yc) ;   % where xc, yc are your circle coordinates

Thank you very much for your feedback. But how can I include the radius of the circle?

You should be knowing this......you said you have a polygon....any ways...to describe a circle..you need a radius r and center c. YOu decide it where you want a circle with what radius. Any more doubts?
