Reduce.RExpr — Type

Reduce expression

Summary:

type RExpr <: Any

Fields:

str::Array{Compat.String,1}

source
Reduce.rcall — Function
rcall(r::RExpr)

Evaluate a Reduce expression.

Examples

julia> R"int(sin(x), x)" |> RExpr |> rcall

source
rcall{T}(e::T)

Evaluate a Julia expression or string using the Reduce interpretor and convert output back into the input type

Examples

julia> rcall("int(sin(y)^2, y)")
"( - cos(y)*sin(y) + y)/2"

julia> rcall(:(int(1/(1+x^2), x)))
:(atan(x))
source

Examples

julia> Reduce.parse(R"sin(i*x)")
:(sin(im * x))
