NARVAL_F_Distance

Perform the Euclidian distance between two network nodes of a graph.

Calling Sequence

[d]=NARVAL_F_Distance(n1,n2,nx,ny)

Parameters

n1 :

network node.

n2 :

network node.

nx :

x-coordinates of network nodes.

ny :

y-coordinates of network nodes.

Description

NARVAL_F_Distance calculates the Euclidian distance between two network nodes n1 and n2. The network nodes coordinates are assumed to be stored inside the vectors nx and ny.

Examples

n=80;//network size
L=1000;//network square area side
dmax=100;//locality radius
[g]=NARVAL_T_LocalityConnex(n,L,dmax);//generation of a random topology in respect with the Locality method. 
N=length(g.node_x);//real network size
[n1,n2]=NARVAL_F_Random_i_j(N);//selection of two distinct nodes
nd=5*ones(1,N);//display the graph
nc=ones(1,N);
nd([n1 n2])=10;
nc([n1 n2])=5;
g.node_border=nd;
g.node_color=nc;
ind=1;//window index
[f]=NARVAL_G_ShowGraph(g,ind);
[d]=NARVAL_F_Distance(n1,n2,g.node_x,g.node_y);//application of NARVAL_F_Distance
