7-Laplace's equation-Iterative method.... >>> Q Jacobi Iteration: m m m uj-1 + u-1₁j + ui+1) + uj+1 4 Note that this formula assumes Ax = Ay. For each interior grid point (i, j), uij at the next iteration (m+1) is found from (6). Once an iteration has been completed for all interior grid points, we compute the infinity norm for vector um+1- um U₁₁jm+1 = If lum+1 um < tol, where tol is a pre-defined tolerance, the iterations terminate and the solution to (5) is um+1, otherwise the iterations continue. To start the iteration (m-0) values must be given for the unknown interior values of uij. These values can be set to zero or interpolated from the known boundary values.
