MATLAB: How to change edge color of ‘biograph’ object

Question

Is there a function similar to "highlight" that I can use for 'biograph' object?

Answer 1

You can modify the color of the edge by modifying the "edges" property of the object:

cm = [0 1 1 0 0;

      1 0 0 1 1;
      1 0 0 0 0;
      0 0 0 0 1;
      1 0 1 0 0];

bg1 = biograph(cm)

% node 4 -> 5

row = 4;

column = 5;

% Use this to modify the color for an edge

idx = (row-1)*size(cm,1) + column

cm1 = reshape(cm',[1,numel(cm)]);

i = sum(cm1(1:idx))

bg1.edges(i).LineColor = [1 0 0];

view(bg1)
