Tile an image into n number of tiles

How to divide an image into n-number of tiles (say n=100) with equal size. I would like to do it with for loop.

With or without overlap? What happens if the number of rows or columns is not a multiple of e.g. 10? How should the tiles be distributed? As 10*10 or 4 * 25? What have you tried so far and which problems occur?

after we tiles it. how can we get the glcm value of each tiles sir ? I mean, how can we do it automatically ? for example.. after we get the first tile we extract glcm from that first tile before move to the second tile and so on. do u have any idea please, sir ?

blocksize = [8 8];
I = imread('cameraman.tif');
I2 = blockproc(I, blocksize, @(block_struct) graycomatrix(block_struct.data), 'trim', false);

The resulting I2 will be (size(I,1)/blocksize * 8) by (size(I,2)/blocksize * 8) with each 8 x 8 subblock being there results of calling graycomatrix on one tile.
