I try to compute the following inner product:
c(a,b) = a * b # inner product between a and b
pp(p1,p2) = (p1,p2) # vec1 with symbolic expressions
ps(s1,s2) = (s1,s2) # vec2 with symbolic expressions
pp*ps # WORKS! (Inner product)
c(pp,ps) # DOESN'T WORK!
where pp and ps are shorthand notations for VectorSpace(SF,2):
symbolic fields (SF) with dimension 2. I don't know why the c(pp,ps)
version doesn't work... Help appreciated.
Do:
def c(a,b): return a*b
Then it will work.
The problem is that the symbolic system does not wrap vectors currently.
Defining a function using the syntax c(a,b)=a*b defines a symbolic
function, which means that (currently) a and b couldn't be vectors.
However, using def, we just define a normal python function, so a and b
could be anything.
Thanks,
Jason
