I'm transferring some code to Cython to speed things up.
In my SAGE/python code, I have a function which takes as one of its
arguments, a function G.
I then declare a series of intermediate functions like this:
Gprime = derivative(G)
Hconj(t) = 1/(2*pi*i)*(Gprime(t)/abs(Gprime(t))/(a-G(t))).conjugate
()
A(t,s) = 1/(2*pi*i)*(Gprime(s)/abs(Gprime(s))/(G(s)-G(t))-(Gprime
(t)/abs(Gprime(t))/(G(s)-G(t))).conjugate())
K(t,s) = sqrt(abs(Gprime(s))) * A(t,s) * sqrt(abs(Gprime(t)))
g(t) = sqrt(abs(Gprime(t)))*Hconj(t)
After GPrime, I have no idea how to transfer this code into Cython.
The f(x) syntax doesn't work, and neither does lambda x: How can I
solve this?
