h*l
发帖数: 19 | 1 Ok, now, in general, this is a Fredholm integral
equation of the 1st kind.
h(r) = \integral (f(r,r')*g(r')*dr') r,r' is n
dim vector.
h(r), f(r,r') is known, we want to find g(r).
For this 3-general problem, f(r,r')=0 if outside
r-3-trangle; f(r,r')=1 if inside r-3-trangle. h(r)=
0.5. Domain is the large trangle.
As we know, Fredholm operator here is a continue
linear operator, and we should find it's spectrum
to solve. Of course, practically, we just use the
technique I proposed |
