function faster than inpolygon()?

Is there a function faster than inpolygon()? or another way to do the intersection ? because it sometimes takes too much time (the program sill busy forever ).

Thank you.

intersection? How you are using inpolygon?

here is the code to understand what I mean :

[A,x,y,I]=geoimread('Cutted1.tif')
rx = shape(1).X(1:end-1);
ry = shape(1).Y(1:end-1);
[X,Y] = meshgrid(x,y);
mask =inpolygon(X,Y,rx,ry);
result= mask.*A;
