24.06.2016 · Partial differential equation in Matlab (incorrect solution) Ask Question Asked 5 years, 5 months ago. Active 5 years, 5 months ago. ... As you've noticed, taking the derivative of an abstract symfun like x(t) is not the same as taking the derivative of a symbolic variable like x (assuming x(t) ...
Symbolic Math Toolbox Partial Differential Equation Toolbox This example shows how to solve a partial differential equation (PDE) of nonlinear heat transfer in a thin plate. The plate is square, and its temperature is fixed along the bottom edge. No heat is transferred from the other three edges since the edges are insulated.

Solve this differential equation. d y d t = t y . First, represent y by using syms to create the symbolic function y(t) . ... Define the equation using == and ...
Differential equations relate a function with one or more of its derivatives. Because such relations are extremely common, differential equations have many prominent applications in real life, and because we live in four dimensions, these equations are often partial differential equations. This section aims to discuss some of the more important ...
