influence

Returns a normalized vector with the influence of the nodes of a graph.

Calling Sequence

influence(I) // Show the influences of the matrix I, always needs the parameter I.
d = influence(I) // Store the influences of the matrix I in the vector f.

Parameters

I:

Matrix to calculate the dependence vector.

f:

Name of the vector to store the influence vector.

Description

This function gives the sum of the columns of the given matrix, that is the influence vector. Note that this works for any matrix, even if have polynomial entries.

Examples

I=[1 0 1;0 2 0;0 0 0]
f = influence(I)
