CoincidentRootLoci :: degree(CoincidentRootLocus)

degree(CoincidentRootLocus) -- compute the degree

Synopsis

Description

The formula for the degree of a coincident root locus X associated with a partition λ=(λ1,...,λd) was determined in the paper by D. Hilbert - Singularitaten der Diskriminantenflache - Math. Ann. 30, 437-441, 1887.

i1 : X = coincidentRootLocus {3,2,2,1,1,1,1}

o1 = CRL(3,2,2,1,1,1,1)

o1 : CoincidentRootLocus
i2 : degree X

o2 = 1260
