How to solve partial differential equation

WebSelect Solution Mesh. Before solving the equation you need to specify the mesh points (t, x) at which you want pdepe to evaluate the solution. Specify the points as vectors t and x.The vectors t and x play different roles in the solver. In particular, the cost and accuracy of the solution depend strongly on the length of the vector x.However, the computation is much … WebFor initial–boundary value partial differential equations with time t and a single spatial variable x, MATLAB has a built-in solver pdepe. 1. 1.1 Single equations Example 1.1. Suppose, for example, that we would like to solve the heat equation u t =u xx u(t,0) = 0, u(t,1) = 1 u(0,x) = 2x 1+x2. (1.1)
