You might not need the polynominals as code in the array. You’re generating a lot of code. It might be faster to only have an array of polynominal coefficients, and run evalpoly
function (horner-rule) on them at runtime.
I suppose you do not have a constant polynominal, but then this is much faster…
function badcode(N::Int)
io = IOBuffer()
println(io, "x = 2; f(x) = x^7+x^6+x^5+x^4+x+1")
println(io, "ll = [")
for i in 1:N
println(io, "[$i, f(x)],")
end
println(io, "]")
return String(take!(io))
end
