PlotSngValDistr

PlotSngValDistr(SngVals, FNmPref, DescStr)

A graph method for directed graphs that plots a histogram distribution of the top 2x SngVals singular values of the adjacency matrix. The function creates three new files: 1) sngDistr.<FNmPref>.plt (the commands used to create the plot), 2) sngDistr.<FNPref>.png (the plot), and 3) sngDistr.<FNmPref>.tab (the plotting data).

Parameters:

• SngVals: integer

  Representing one half the desired number of singular values.

• FNmPref: string

  A string representing the preferred output file name.

• DescStr: string

  Description of the graph. The string should be non-empty.

Return value:

• None

The following example shows how to use PlotSngValDistr() for TNGraph:

import snap

Graph = snap.GenRndGnm(snap.TNGraph, 100, 5000)
Graph.PlotSngValDistr(50, "title", "SngVal Distribution")
