Contour

contour(f; options...)

Compute the contour 𝐶(𝑓) of the amoeba $\mathcal{A}(f)$.

Example

@polyvar x y

contour(x^2+y^2+1)

# custom domain
contour(x^2+y^2+1, domain=(-5, 5, -5, 5))

Options

• domain: A tuple in the form (xmin, xmax, ymin, ymax) which defines a section Ω

for which the contour 𝐶(𝑓) is computed.

• membership_options: The options for the membership test
• res=(600,600): The resolution with which starting points are sampled
• samples_off_axis=2*MP.maxdegree(p)^2: The number of sample points per off-axis.
