Contents

Description

The MATEIG block computes the eigenvalues and the eigenvectors of a square input matrix U. When the decomposition type is set to:

The equivalent of the MATEIG block in Scilab is spec

Parameters

Default properties

Example

A = [1 12 32 ; 21 35 46 ; 70 8 19]
When the "Decomposition type" is set to one the output is y = [-35.649 ; 14.279 ; 76.369]
When the "Decomposition type" is set to two the outputs are:
y1 = [-35.649 0.000 0.000 ; 0.000 14.279 0.000 ; 0.000 0.000 76.369]
y2 = [0.557 0.080 0.349 ; 0.330 -0.922 0.770 ; -0.762 0.379 0.533]

Eigenvalues example: spec([sin(t) 0; 0 t]) = [sin(t); t]
