Reference discussed the convergence analysis of orthogonal spline collocation for Burgers’ equation using the extrapolated Crank–Nicholson method for discretization in time.
WebWe instead use smart numerical algorithms to solve the system (4.4). For instance, one can use the Thomas tridiagonal algorithm for this particular system, which is a simplified version of Gaussian elimination. • We only obtain an approximation ui ≈ u(xi ). To reduce the approximation error, we could reduce the mesh size h.
