Questions tagged [pde]

Use this tag for questions about partial differential equations. For questions about the Eclipse Plugin Development Environment, use eclipse-pde instead.

Partial Differential Equations are differential equations that contain unknown multivariable functions and their partial derivatives. See [http://en.wikipedia.org/wiki/Partial_differential_equation][1]

The Eclipse Plug-in Development Environment (PDE) provides tools to create, develop, test, debug, build and deploy Eclipse plug-ins, fragments, features, update sites and RCP products. PDE also provides comprehensive OSGi tooling. See [http://www.eclipse.org/pde/][2]

Questions about the Eclipse Plug-in Development Environment are better tagged as 'eclipse-pde'.

How to solve two coupled nonlinear Schrodinger equations in MATLAB?

The two coupled equations are as follows: where i->sqrt(-1); 'u_t' refers to the first order derivative w.r.t. the time 't', 'u_z' is the first order derivative w.r.t. 'z', similarly, 'u_tt' means second order derivative w.r.t. time. |u|^2 is…
