Bugfixes
Fix show for variables with indices larger than 9
We fixed a small bug in the new unicode printing for for variables with indices larger than 9.
Improve printing
We now have by default a very nice unicode output for polynomials
julia> @polyvar a b c;
julia> (a^2+b-c)^2
a⁴ + 2a²b - 2a²c + b² - 2bc + c²
julia> @polyvar x[1:3] y[1:3];
julia> prod(cross(x, y))
-x₁²x₂y₂y₃² + x₁²x₃y₂²y₃ + x₁x₂²y₁y₃² - x₁x₃²y₁y₂² - x₂²x₃y₁²y₃ + x₂x₃²y₁²y₂
julia> @polyvar X[1:3, 1:2, 4:5]; # Only DynamicPolynomials currently
julia> X
3×2×2 Array{PolyVar{true},3}:
[:, :, 1] =
X₁₋₁₋₄ X₁₋₂₋₄
X₂₋₁₋₄ X₂₋₂₋₄
X₃₋₁₋₄ X₃₋₂₋₄
[:, :, 2] =
X₁₋₁₋₅ X₁₋₂₋₅
X₂₋₁₋₅ X₂₋₂₋₅
X₃₋₁₋₅ X₃₋₂₋₅
Also the print function now creates an output which can be copy-pasted back to a file
julia> @polyvar x[1:3]
(PolyVar{true}[x₁, x₂, x₃],)
julia> sum(x)*x[2]
x₁x₂ + x₂² + x₂x₃
julia> print(sum(x)*x[2])
x[1]*x[2] + x[2]^2 + x[2]*x[3]If this printing doesn't fit your needs you can use the name_base_indices function to create your own custom printing of variables.
Minor interface update
We add the name_base_indices function to make it possible to improve the printing of polynomials.
