charpoly

  

compute the characteristic polynomial of a matrix

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

charpoly(A, lambda)

Parameters

A

-

square matrix

lambda

-

name or algebraic expression

Description

• 

Important: The linalg package has been deprecated. Use the superseding command LinearAlgebra[CharacteristicPolynomial], instead.

  

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

• 

The function charpoly computes the characteristic polynomial of the matrix A=detIλA, where I is the identity matrix and n is the dimension of A.

• 

The command with(linalg,charpoly) allows the use of the abbreviated form of this command.
