matlab and derivative
I read through this paper and to be honest it looks more like a curiosity than anything substantial. If the object is to study symmetries and invariances of maxwell's equations (as an aid in simplifying some field calculations), then I'm sure I've seen better settings for the problem than here...but these can sometimes be too theoretical. If I remember right,for example, maxwell's equations (in vaccum) are inavariant under all conformal transformations (which include lorentz transformations), they are also invariant under "duality" (E,B) -> (B,-E) In the presence of sources (currents and charges) the symmetries are different, but I don't remember the details of that. So maybe conformal symmetries is a
better subject to look at than fractional calculus, unless fractional
differentiation is actually conformal!...my math isn't good enough to answer that. Come to think of it my physics knowledge isn't that good in this area either, so maybe you shouldn't quote me on any of the above!
