  • Documentation
    • Need at least one example showing easy calculations/plotting
    • need another example showing fits/gradients

Usage

Wien's law

Using Optim.jl we can numerically maximize the blackbody function to see how closely it agrees with Wien's law.

using Optim

# function to minimize
Teff = 5796
f(λ) = -blackbody(λ, Teff)

# bounded between 1 picometer and 10 m
res = Optim.optimize(f, 1e-12, 10)

λ = Optim.minimizer(res)
isapprox(λ, 2.898e-3 / Teff; rtol=1e-4)
