One such class is partial differential equations pdes. A partial differential equation is said to be quasilinear if it is linear with respect to all the highest order derivatives of the unknown function. The symbolic capabilities of the wolfram language make it possible to efficiently compute solutions from pde models expressed as. The next step is the implementation of the ipmethod by using standard tool which leads to a oo code that uses some of matlab s pde toolbox functionality. Further, we integrate the ipmethod in existing pde software like comsol multiphysics.
