Rearrange the matrix into a vector and do RLE on that.

For images you might wish to investigate zig-zag rearrangements of the matrix into a vector, as that apparently gets better RLE for blocks of the same color.

[Jitesh Bhanushali]

sir what is command for rearranging matrix into vector?

[Walter Roberson]

One of them is reshape(). The zig-zag approach would not use reshape() though.
