Abstract
Millions of people are infected by Dengue every year. So to understand its mechanism, we have considered one of the recent fractional and nonlinear Dengue models proposed by Diethelm. However, the problem is that its exact solution is not known. Therefore, an extended Haar wavelets based numerical method has been implemented to solve it. Although Haar wavelets-based numerical methods have been used by researchers in recent years its theoretical error analysis over the extended interval , , has never been done before for fractional dynamical systems. It helps to show the convergence of a sequence of approximate solutions to the exact solution. Also, the derived error bound gives a guarantee that error in the considered Haar approximate solution cannot exceed its bound. And any desired accuracy can be obtained by increasing the number of Haar wavelets in the approximate solution.
