See my function "seqle" on FileExchange. It may not be as compact, but it's easy to use and both encodes and decodes.
The problem statement would have been clearer if the principle of RLE had been explained with an encoding example first. Alternatively, it would have been useful to explicitly mention that the data in vector x is being read pairwise.
ugly but more fun than loops!
note: repelem did not exist back when this problem was created
