I am trying to develop my own code based on example 23 (\partial_t U = i/(2k)\nabla^2U), and am trying to understand the purpose of the laplace-matrix. Why is it used in order to multiply in both sides, in comparison with the weak formulation (\nabla\phi_i,\nabla\phi_j) and the assembly of the usual cell matrix? Assumed I have to split my U into a real and an imaginary value, is the approach with the Laplace-matrix better, or the split into the weak formulation and the accompanying matrices on both sides?
