to flip an image block across main diagonal line y=x

I have an image of size 256x256 and it is divided into 58081 overlapping blocks of size 16x16. I flipped each and every block vertically and horizontally using flipdim(image block, dimension)function. Is there any function to flip every block across the main diagonal line y=x?

If they're overlapping , then it must look like a totally unrecognizable mess as some pixels get flipped over and over and over again and end up who knows where.

transpose

img_block_diag = transpose(img_block);

It works. Thank you very much.
