A 2D cell network can be created from a collection of vertices, edges and cells.

Each vertex is a 2D point and a list of vertices can be created as a nx2 array.

Each edge is a 2D arc with an optional age (lineage). A list of edges can be represented as a nx4 array where each row is composed of the following element:

• the first element is the index of the starting vertex,
• the second element is the index of the ending vertex,
• the third element is the oriented angle (in radians) formed between the arc and the chord length joining the 2 vertices. 0 means a straight line,
• the fourth (optional) element is the age of the edge.

Cells are directed cycles i.e. cyclic sequences of vertices and edges. A list of cells can be represented as a cell array where is cell contains of vector with the edge index.

The following example create a triangular cell:

% Create a list of 2D vertices
V=[0 0;
  1 0;
  0 1;];

% Create a list of edges
E = [1 2 0;
     2 3 pi/4;
     3 1 0;];

% Create a cell array of cells
C = {[1 2 3]};

% Create the cellNetwork object
N = cellNetwork(V,E,C);

% Plot the cellNetwork object
h = plot(N, 'o-r')
