Hello guys, I notice there are [Fresnel integral](https://specialfunctions.juliamath.org/stable/functions_overview/#[Error-Functions,-Dawson%E2%80%99s-and-Fresnel-Integrals](https://dlmf.nist.gov/7)-1) related docs there, but I don't see any implementation about Fresnel integral or [auxiliary Fresnel integral](http://www.mymathlib.com/functions/fresnel_sin_cos_integrals.html), so I think this part is...

After the discretization, the linear fractional differential equation is transformed to a linear problem: $$Au=b$$ The current solver is the default solver in Julia, we can use the SciML LinearSolve.jl:...

Like the ```ODEFunction``` in DifferentialEquations.jl, we can provide ```FODEFunction``` to pass the jacobian and reduce the jacobian generating cost by ForwardDiff.jl
