From: moi cépatézognon on 19 Jul 2010 05:49 Hi, I'm trying to solve a problem with the pde toolbox and I need to evaluate the gradient of my solution on the boundaries of my domain. I've tried the function pdegrad, but it only gives the value of the gradient on the center of each triangle, not on the points of the boundaries. Do you have an idea how to do it? |
