mpprojspec - maxplus spectral projector

Calling Sequence

[P,n]=eigenspace(A)

Parameters

Description

Computes the spectral projector associated with the largest eigenvalue of a maxplus matrix and gives the number of strongly connected components of the critical graph which is the dimension of the corresponding spectral space.

Examples

[P,n]=mpprojspec(#(1))
a=#([1,2;3,4]);[P,n]=mpprojspec(a)
P*a==P*4
a=#([1,0;0,1]); [P,n]=mpprojspec(a)
P*a==P*1
