Numerical Solution of a Fractional Model for HIV Infection of CD4+T Cells via Legendre Multiwavelet Functions.

In this paper, we introduce a Galerkin method based on Legendre multiwavelet functions to obtain approximate solutions of a fractional model for HIV infection of CD4⁺T cells corresponding to a class of systems of nonlinear fractional differential equations. The method converts the model problem into a system of nonlinear algebraic equations. A numerical example is included to demonstrate the validity and applicability of the technique and the results are compared with those obtained by existing methods. [ABSTRACT FROM AUTHOR]
