it doesnt work cause i dont want a magic matrix.i want my matrix. its an image (black letter A in a white background) having a size of 128X128.

I want to put this small letter in a big white background (512X512)

Well let's see; how hard is it to change your choice of matrices? You could use:
>>A = magic(128)
>>A = rand(128)
>>A = zeros(128)
>>A = ones(128)
>>A = your_matrix
>>A = pascal(128)

One of those 6 probably should satisfy your needs.

Then do exactly what us or I said. Oh, I forgot, you might also have to change a number or something too. We provided the logic; now you have to make it work for your application.

And us posted _an example_ of the technique you need to use. All you need
to do is adapt it slightly to use your image instead of the _sample_ data us
used.
