Is there an easy way to transpose a matrix in GNU-Emacs ? 1 2 3 4 5 1 6 2 1 9 6 7 8 9 2 2 7 4 3 8 2 4 6 8 0 ====> 3 8 6 5 7 1 3 5 7 9 4 9 8 7 6 9 8 7 6 5 5 2 0 9 5 2. Is there an easy way to rotate a rectangular of text +90/-90 degrees ? 1 2 3 4 5 9 1 2 6 1 6 7 8 9 2 8 3 4 7 2 2 4 6 8 0 =====> 7 5 6 8 3 1 3 5 7 9 6 7 8 9 4 9 8 7 6 5 5 9 0 2 5 3. Is there an easy way to mirror a rectangular of text (vertical/horizontal) ? 4. How about reverse a line or reverse a region ? Above questions should be applied to both character and word boundary. Can anyone out there give me some advices ? Ko-Haw Nieh General Electric Company Corporate Research and Development nieh@ge-crd.arpa 518-387-7431
