Compute nearest neighbour matrix for TFCE.
Description
Given a Tx3 matrix (T = number of triangles in the triangular mesh) containing vertices IDs of each triangle, this function computes a Ex2 matrix containing the mesh edges (E = numbr of edges).
To each mesh corresponds a unique NNmatrix, which is exploited by TFCE function to compute TFCE scores. In order to speed up TFCE execution time, repetitions like (A,B) and (B,A) are avoided.
Usage
computeNNmatrix(triangles)
Arguments
triangles
a Tx3 matrix (T = number of triangles in the triangular mesh) containing vertices IDs of each triangle.
Value
A Ex2 matrix containing the mesh edges (E = numbr of edges)
Examples
NNmatrix <- computeNNmatrix(triangles)
