Explicit and Implicit Solutions to 2-D Heat Equation

The error in a method's solution is defined as the difference between the approximation and the exact analytical solution. The two sources of error in finite difference methods are round-off error, the loss of precision due to computer rounding of decimal quantities, and truncation error or discretization error, the difference between the exact solution of the original differential equa… Witryna5 maj 2024 · This uses implicit finite difference method.
