Dear all,
Is there a way with the getfem python interface to assembly the matrix associated to the interpolation matrix of a first derivative evaluation of a fem (or its full gradient).
I found
Mi = asm_interpolation_matrix(MeshFem mf, vec pts)
for the evaluation of the function u = MeshFem mf itself, but I was not able to identify the relevant generalization for derivatives of u: \partial u_x, \partial u_y, etc.
Thanks a lot for this great library,
best, Edouard.
