Eugenfunction is often a misspelling of eigenvalue.


Eugenfunction has no English definition.

As a noun eigenvalue

is a scalar, \lambda\!, such that there exists a vector x (the corresponding eigenvector) for which the of x under a given linear operator \rm A\! is equal to the of x under multiplication by \lambda; i.e. {\rm A} x = \lambda x\!

eigenvalue

English

Noun

(en noun)
  • (linear algebra) A scalar, \lambda\!, such that there exists a vector x (the corresponding eigenvector) for which the image of x under a given linear operator \rm A\! is equal to the image of x under multiplication by \lambda; i.e. {\rm A} x = \lambda x\!
    • ''The eigenvalues \lambda\! of a square transformation matrix \rm M\! may be found by solving \det({\rm M} - \lambda {\rm I}) = 0\! .

    Usage notes

    When unqualified, as in the above example, eigenvalue conventionally refers to a right eigenvalue, characterised by {\rm M} x = \lambda x\! for some right eigenvector x\!. Left eigenvalues, charactarised by y {\rm M} = y \lambda\! also exist with associated left eigenvectors y\!. For commutative operators, the left eigenvalues and right eigenvalues will be the same, and are referred to as eigenvalues with no qualifier.
