quadrilateral_mesh_rcm, an Octave code which computes the Reverse Cuthill-McKee (RCM) reordering for nodes in a mesh of 4-node quadrilaterals.
The user supplies a node file and an element file, containing the coordinates of the nodes, and the indices of the nodes that make up each element.
The program reads the data, computes the adjacency information, carries out the RCM algorithm to get the permutation, applies the permutation to the nodes and elements, and writes out new node and element files that correspond to the RCM permutation.
