# findHeft -- find a heft vector for a list of degrees

## Synopsis

• Usage:
findHeft(degs, DegreeRank => r)
• Inputs:
• degs, a list, of multi-degrees, each of which is a list of integers of fixed length r
• Optional inputs:
• DegreeRank => an integer, default value null
• Outputs:
• a list, of integers of length r, or
• null, if there is none

## Description

findHeft returns a weight co-vector whose dot product with each member of degs is strictly positive.
