Well, that was not only quick and helpful - it worked! Thank you.

The failure is in the command

imagesc(blurimage)

the problem is that blurimage is complex. The imaginary part is at most 1.e-13 (probably because of rounding errors), and
imagesc cannot display complex matrices.
In matlab it works becuase the imaginary part of blurimage
is zero.

You can try
imagesc(real(blurimage))

and
imagesc(imag(blurimage))
