Description

I have seen a discussion here about solving Volterra eq of the second kind:
https://discourse.julialang.org/t/using-approxfun-jl-to-solve-a-volterra-equation-of-the-second-kind/40203
But I failed to adapt it to my case: $B(y) = f(y) + \int_0^y K(x, y)*B(x) dx$. For example, say K(x, y) = 1 - exp(x+y)
f(x) = 3x^3.
How to compute B()?

Besides, I can not find any description of that Volterra() in ApproxFun.jl

Research direction

Start with the linked Discourse discussion and the ApproxFun.jl Volterra() entry point mentioned in the issue. Document how to solve the stated second-kind Volterra equation, including the provided kernel and f(x)=3x^3 example, so users can compute B() and find the API description.
