Eigvc; Eigvl - Casio Algebra FX 2.0 PLUS User Manual

Using the CAS (Computer Algebra System) Mode
u EigVc
Function: Returns the eigenvector of a matrix.
Syntax: EigVc Mat
Example To determine the eigenvector of the matrix below

b,d!-( ] )!-( ] )w
Eigenvectors are stacked vertically on the display.
In this example, (0.894427191 0.4472135955) are the eigenvectors that correspond to 5,
while (–0.894427191 0.4472135955) are the eigenvectors that correspond to 1.
An eigenvector has an infinite number of solutions. The eigenvector displayed by this
command is the one with a size of 1.
u EigVl
Function: Returns the eigenvalue of a matrix.
Syntax: EigVl Mat
Example To determine the eigenvalue of the matrix below
