### Function Reference: `bim3c_tri_to_nodes`

Function File: u_nod = bim3c_tri_to_nodes (mesh, u_tri)
Function File: u_nod = bim3c_tri_to_nodes (m_tri, u_tri)
Function File: [u_nod, m_tri] = bim3c_tri_to_nodes ( ... )

Compute interpolated values at triangle nodes u_nod given values at tetrahedral centers of mass u_tri. If called with more than one output, also return the interpolation matrix m_tri such that `u_nod = m_tri * u_tri`. If repeatedly performing interpolation on the same mesh the matrix m_tri obtained by a previous call to `bim2c_tri_to_nodes` may be passed as input to avoid unnecessary computations.
