There are also some toolboxes that can be used for fractional differential equations, here we make a survey of all these toolboxes and have a more intuitive perspective.
FOTF toolbox is a Matlab toolbox developed by Prof Dingyu Xue, with fractional calculus, fractional differential equations and fractional order systems integrated together. To be honest, FOTF has a great impact on FractionalDiffEq.jl, all of the algorithms in FOTF toolbox is all supported in FractionalDiffEq.jl
The corresponding matrix discretization paper and toolbox is developed by Prof Igor Podlubny. The corresponding matrix discretization method in FractionalDiffEq.jl is
fodeint: With explicit one-step Adams-Bashforth (Euler) method.
Don't see any packages for fractional differential equations.
