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.

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;
