dim(CoincidentRootLocus) -- compute the dimension

Synopsis

• Function: dim

• Usage:

  dim X

• Inputs:
  • X, a coincident root locus
• Outputs:
  • an integer, the dimension of X as a projective variety

Description

The dimension of a coincident root locus $X$ associated with a partition $\lambda=(\lambda_1,\ldots,\lambda_d)$ is $d$, the number of parts of $\lambda$.

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

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

o1 : Coincident root locus

i2 : dim X

o2 = 7
