# degreeOfJetSeparation -- computes the degree of jetSeperation at a given point

## Synopsis

• Usage:
degreeOfJetSeperation(A,pt)
• Inputs:
• A, , or a list where the columns are lattice points
• pt, , a point as a column vector
• Outputs:
• k, an integer, the maximal such that the embedding specified by A is k-jet spanned at pt

## Description

degreeOfJetSeparation is a function. Given the set of lattice points of and a point it computes the maximal k such that the associated line bundle is k-jet spanned at the point
