【Abstract】 In this paper,Bernstein polynomials are used to seek the numerical solution of a class of variable order fractional differential equation.With the differential operator matrix of first order and the fractional operator matrix of Bernstein polynomials,the initial equation is transformed into the products of several dependent matrixes which can also be regarded as the system of linear equations after dispersing the variable.By solving the system of linear equations,the numerical solutions are acquired.Numerical examples are provided to show that the method is computationally efficient and accurate.更多还原
