Using the Action Menu

ueigVl

Function: Returns a list that contains the eigenvalue(s) of a square matrix.

Syntax: eigVl (Mat [ ) ]

Example: To obtain the eigenvalue(s) of the matrix [[3,4] [1,3]]

Menu Item: [Action][Matrix-Calculation][eigVl]

ueigVc

Function: Returns a matrix in which each column represents an eigenvector of a square matrix.

•Since an eigenvector usually cannot be determined uniquely, it is standardized as

follows to its norm, which is 1:

When V = [x1, x2, ..., xn], ( x12 +  x22 + .... +  xn2) = 1.

Syntax: eigVc (Mat [ ) ]

Example: To obtain the eigenvector(s) of the matrix [[3,4] [1,3]]

Menu Item: [Action][Matrix-Calculation][eigVc]
