Abstract
In this paper, we make the first attempt to apply polynomial point interpolation collocation method for solving spatial fractional differential equation with two-side derivative. Firstly, numerical approxi-mation scheme was obtained by polynomial point interpolation. Then numerical examples, discretizing space variable with both regular nodes and irregular nodes, had good approximation results, which testified the va-lidity of the proposed numerical method.关键词
