FArrayMod.jl

provides the ability to use arbitrary starting indices for arrays in Julia programming language.

julia> using FArrayMod

julia> y = FArray(Float64, -1:1, -7:7, -128:512, -5:5, -1:1, -3:3, -2:2, -1:1);

julia> y[-1,-7,-128,-5,-1,-3,-2,-1] = 14
14

julia> y[-1,-7,-128,-5,-1,-3,-2,-1] += 5

The main purpose of this package is to simplify translation from Fortran codes intensively using Fortran arrays with negative and zero starting indices, such as

• the codes accompanying the book Numerical Solution of Hyperbolic Partial Differential Equations by prof. John A. Trangenstein Please refer here and here

• Clawpack (stands for Conservation Laws Package) by prof. Randall J. LeVeque

  • classic ClawPack

  • ClawPack 5.0
