Haar wavelet approach to nonlinear stiff systems

The problem of nonlinear stiff systems which refers to the change in the independence variables due to change of the components contained in the solutio of a system was solved using Haar wavelets. The algorithm was applied to take the advantages of its fast, local and multiplicative properties. The simulation suggested that the computation time was reduced to one tenth of the Runge-Kutta-Fehlberg approach.
