Numerical Analysis WSGD Scheme for One- and Two-Dimensional Distributed Order Fractional Reaction–Diffusion Equation with Collocation Method via Fractional B-Spline

Abstract The main propose of this paper is presenting an efficient numerical scheme to solve WSGD for one- and two-dimensional distributed order fractional reaction–diffusion equation. proposed method based on B-spline basics in collocation which involve Caputo-type derivatives $$0 < \alpha 1$$ 0 < α 1 . most significant privilege quite accurate it requires relatively less computational work. solution consideration problem transmute the linear system algebraic equations can be solved by a suitable method. finally, several Scheme
