44 Alphabetical Listing
eff()
Catalog >
eff(nominalRate,CpY) ⇒ value
Financial function that converts the nominal
interest rate nominalRate to an annual
effective rate, given CpY as the number of
compounding periods per year.
nominalRate must be a real number, and
CpY must be a real number > 0.
Note: See also nom(), page 102.
eigVc()
Catalog >
eigVc(squareMatrix) ⇒ matrix
Returns a matrix containing the
eigenvectors for a real or complex
squareMatrix, where each column in the
result corresponds to an eigenvalue. Note
that an eigenvector is not unique; it may be
scaled by any constant factor. The
eigenvectors are normalized, meaning that:
if V = [x
1
, x
2
, … , x
n
]
then x
1
2
+x
2
2
+ … +x
n
2
= 1
squareMatrix is first balanced with
similarity transformations until the row and
column norms are as close to the same
value as possible. The squareMatrix is then
reduced to upper Hessenberg form and the
eigenvectors are computed via a Schur
factorization.

eigVl()
Catalog >
eigVl(squareMatrix) ⇒ list
Returns a list of the eigenvalues of a real or
complex squareMatrix.
squareMatrix is first balanced with
similarity transformations until the row and
column norms are as close to the same
value as possible. The squareMatrix is then
reduced to upper Hessenberg form and the
eigenvalues are computed from the upper
Hessenberg matrix.
