Hi all, I want to model an equation using du/dx, but there's not a type to specify it. I am trying to solve an elliptic equation, but it contains du/dx. I read the documentations, and it is told to use 'ux' for du/dx in 'f' parameter specifications. I have tried that, but it won't work, producing an error.
How to specify du/dx or du/dy in matlab pde-toolbox?
Thank you.

ux, uy should be the way to specify the first derivatives. Could you post your PDE and the error that you are seeing?
