The interpolation approximation is important, because the computation of inner product is avoided.

插值逼近的重要性在于它避免了计算内积的麻烦.

In the inner product space, the existence theory of best approximation element was obtained and described.

获得了内积空间关于弱闭凸集的最佳逼近元的存在性及其刻划定理.

The inner product algorithm and cross multiply algorithm in the vector calculation are used to deduce active power and reactive power.

利用矢量运算中的内积算法和叉乘算法来推导有功功率和无功功率。

The inner product in interpolation interpretation is a residual and therefore can be precomputed successively.

产品的内在插值的解释是剩余，因此可算成功。
