You'll have to be clearer about what you want. Providing an example of input and desired output really helps. What does considering a 7 by 7 matrix in an image mean?

If you want a 7x7 sliding window, you would use convolution
out=conv2(yourImage,ones(7)/49,'valid');
If instead you want to decompose your image into non-overlapping 7x7 tiles, then I would recommend sepblockfun (Download).
out=sepblockfun(yourImage,[7,7],'mean');

As Matt wrote, "If you want a 7x7 sliding window, you would use convolution" and he gave you the code.
