In this work, we solve nonlinear Duffing fractional differential equations with integral boundary conditions in the Caputo fractional order derivative sense. First, we introduce the cubic Hermite spline functions and give some pr

Abstract In this paper, the vector extension operation is proposed to replace the de Boor‐Cox formula for a fast algorithm to B‐spline basis functions. This B‐spline basis function based on vector extending operation is implemented in the class

The generalization of the classical FitzHugh–Nagumo model provides a more accurate description of the physical phenomena of neurons by incorporating both nonlinearity and fractional derivatives. In this article, we present a numerical method for so
