Tri{T<:Number, S<:Integer} <: CyclicSchedule
Tri(;λ0, λ1, period)

A triangle wave schedule with period. The output conforms to

abs(λ0 - λ1) * (2 / π) * abs(asin(sin(π * (t - 1) / period))) + min(λ0, λ1)

Arguments

• λ0::Number: the start value
• λ1::Number: the end value
• period::Integer: the period
