Using Command-Line Functions

Although the `pdetool` GUI provides a convenient working environment, there are situations where the flexibility of using the command-line functions is needed. These include

- Geometrical shapes other than straight lines, circular arcs, and elliptical arcs
- Nonstandard boundary conditions
- Complicated PDE or boundary condition coefficients
- More than two dependent variables in the system case
- Nonlocal solution constraints
- Special solution data processing and presentation itemize

The GUI can still be a valuable aid in some of the situations presented above, if part of the modeling is done using the GUI and then made available for command-line use through the extensive data export facilities of the GUI.
