C = imread('lena.png');
lab = rgb2lab(C);
L=lab(:,:,3);
imshow(L);
output_size = max(size(L));
D = 315.25;
dsensor3 = 0.1985;
[F3, sensor_pos3, fan_rot_angles3] = fanbeam(L,D,...
'FanSensorSpacing',dsensor3);
imshow(F3);
Ifan3 = ifanbeam(F3,D,'FanSensorSpacing',dsensor3,'OutputSize',output_size);
figure, imshow(Ifan3)
I want to divite the F3 into 4*4 block...but the size of F3 i am getting is 361*360....now what can i do?

Either crop it, enlarge it, or resize it.
