eigenstrapping.geometry.calc_eig

eigenstrapping.geometry.calc_eig(mesh, num_modes, use_cholmod=False, remove_zero=False)

Calculate the eigenvalues and eigenmodes of a surface.

Parameters:

• mesh (lapy compatible object) – Loaded vtk object corresponding to a surface mesh

• num_modes (int) – Number of eigenmodes to be calculated

Returns:

• evals (array (num_modes x 1)) – Eigenvalues

• emodes (array (number of surface points x num_modes)) – Eigenmodes
