I/O, Saving, and Latex
Note that Julia’s standard I/O functionality can be used to save Symbolics expressions out to files. For example, here we will generate an in-place version of f
and save the anonymous function to a .jl
file:
using Symbolics
@variables u[1:3]
function f(u)
[u[1]-u[3],u[1]^2-u[2],u[3]+u[2]]
end
ex1, ex2 = build_function(f(u),u)
write("function.jl", string(ex2))
850
Now we can do something like:
g = include("function.jl")
#1 (generic function with 1 method)
and that will load the function back in. Note that this can be done to save the transformation results of Symbolics.jl so that they can be stored and used in a precompiled Julia package.
