对连续函数进行离散化,给出离散序列的分数阶和分算子与分数阶差分算子的解析表达式,证明了两算子满足交换律、指数率与互逆性.
Transform the continuous function to discrete sequence, put forward analytical expression of discrete fractional summation operator and difference operator, then prove the exponential law, commutative law and mutual invertibility of the two operators.
