Generate code (generate.jl) [ edit ]

using Oscar

R = root_system(:A, 6)
save("data.mrdi", positive_root(R, n_positive_roots(R)))

Data outputs

Profiles: OSCAR v1.0

Not available for OSCAR v1.0.

In OSCAR v1.0-1.1 the generator fails with `Unsupported type 'Oscar.LieAlgebras.RootSpaceElem' for encoding`.
