Hello,
I'm trying to understand this program:
http://demonstrations.wolfram.com/data/005175/0005/RepresentationOfDiffractionByVectorSummation/RepresentationOfDiffractionByVectorSummation-source.nb
But when I download it or look at it I get this error:
The stretchable character 0xf3a5 in the Mathematica1Mono font (size 13) has a repeating piece (0x80) that is zero size.
But some of the notation looks like gobligook so it's hard to see what's going on in some places.
If someone could explain this error and provide a solution so that I can learn the algorithm/code that would be great!
Here is a screenshot:
