Hi I have a matrix of numbers representing the nodal points as follows: Element No. Nodes
1 1 2 3 4 2 5 6 7 8 3 2 3 9 10 ........................... ........................... x 9 10 11 12 ........................... so this is a matrix of numbers 4 x n Elements 1 and 3 are neighbours (as they share nodes 2 3). Similarly elements 3 and x are neighbours (they share nodes 9 and 10). I want to sort the matrix in such a way all the elements are sequentially arranged. How could I script it? can any one help me?
