You need to use FEX::MAT2TILES. Download this package and place it in MATLAB path

imageBlocks = mat2tiles(Image, [3 3])

imageBlocks will contain cell array of the 3x3 pixel blocks.

You need to download the File Exchange Contribution and unzip it into a convenient directory, and then use pathtool to add that directory to your MATLAB path.
