numericalImageDegree W
numericalImageDegree(F, I)
This method computes the degree of the image of a variety, by computing a pseudo-witness set for the image (cf. pseudo-witness set for more on the techniques and options used).
If a pseudo-witness set has already been computed, then to avoid repetitive calculation one may run this function with the pseudo-witness set as input.
The following example determines the degree of the Grassmannian $Gr(2,4)$ of $P^1$'s in $P^3$, under its Plücker embedding in $P^5$.
