    Finite Differences in Mathcad 14

    Hi everybody!

    I have updated to Mathcad14 and have some troubles with some algorithms. They work correctly on my old old Mathcad 2001 but doesn't on my new version..
    I have to solve 2D differential equations, and used to do it by finite differences on the 2001 version with the algoritm that I'd learned at Univeristy. The algorithm consists on a Given-Find function with all the equations having the variables as points of a Matrix. So they are defined on two for loops (one for each dimension).
    I could write one equation for each node to override the need of using a program loop in this particular example, becouse there are only 25 nodes, but Its imposible to do it with bigger systems...
    I've attached the Algorithm, so you can check it.
    Any advice is welcome!
    Thanks, and a nice year to everybody!
