1-D Partial Differential Equations

1-D solver for parabolic and elliptic PDEs

Partial differential equations contain partial derivatives of functions that depend on several variables. MATLAB^®lets you solve parabolic and elliptic PDEs for a function of time and one spatial variable. For more information, seeSolving Partial Differential Equations.

Partial Differential Equation Toolbox™extends this functionality to problems in 2-D and 3-D with Dirichlet and Neumann boundary conditions.
