`@vars`, `@params`

Creates a vector of TPSs corresponding to each variable/parameter in the GTPSA

Syntax

Δx  = @vars(descriptor [,complex=bool] [, dynamic=bool])

Δk  = @params(descriptor [,complex=bool] [, dynamic=bool])

Description

Δx = @vars(descriptor) creates a vector of TPSs corresponding to each of the variables in the GTPSA descriptor

Δk = @params(descriptor) creates a vector of TPSs corresponding to each of the parameters in the GTPSA descriptor`

Optional Argument

complex if true, will return the corresponding TPSs as ComplexTPS64. Default is false.

dynamic if true, will use dynamic Descriptor resolution for the returned TPSs

Examples

julia> d5 = Descriptor(3, 5, 2, 5); # 3 vars, 2 params, all to order 5
julia> Δx = @vars(d5)3-element Vector{TPS64{Descriptor(NV=3, MO=5, NP=2, PO=5)}}:
