I have been using code for the code for the ecg compression from the following link http://www.mathworks.com/matlabcentral/fileexchange/49712-ecg-compression-based-on-dct-and-rle

but in this code for inverse run length coding 1-dimensional signal but i needed that for the 2-dimensional inverse run length encoding so pls kindly help me out of this as soon as possible.

inverse run-length the 1D encoding, and reshape() the result to be 2D .

Well, where did you find your 2D RLE code? There are multiple ways of doing 2D RLE.

The easiest way to do 2D RLE encoding is to take the input signal, reshape it into a vector, and do 1D RLE encoding on the vector, giving an output. Then afterwards, do inverse 1D RLE on that output, giving a 1D vector, which you then reshape() to be a 2D array.
