著名的Bernstein算子的最佳逼近度为O(1/n),引进一类新的Bernstein型算子,当f∈C[0,1]时,它有较高的逼近度,给出其逼近正定理,此定理推广了以前有关的Bernstein算子的结果.
For well known Bernstein operator, the best approximation degree is O(1/n). By introducing a new Bernstein-type operator which has higher approximation degree for f∈C[0,1], Its direct approximation theorem is obtained. These results extend the provious results of Bernstein operator.
