dot product

dot product什么意思,dot product翻译

基本解释

un.: 点积；标量积
网络: 点乘；点乘积

英汉解释

• 标量积

• 点积

例句

• Since scalars are independent of the coordinate system, the dot product of two vectors is called a scalar invariant.

  因为标量与坐标系无关，故两个矢量的点积称为标量不变量。

• If I take the dot product But now, what does it mean that the dot product between OP and A is zero?

  如果我用OP·A我就得到了，那么OP和A的点积是0代表了什么呢？

• It"s the dot product between the normal vector of a plane and the vector along the line.

  这是平面法向量，和沿直线向量的点积。

• And I can rewrite this in vector form as the gradient dot product the amount by which the position vector has changed.

  可以把这些用向量形式重新写下来，就是梯度向量和位置改变量的点积。

• Also note that you can calculate the dot product only if the two vectors have the same number of components .

  另外请注意，只有当两个矢量的组件数相同时，才能计算点积。

• But, you will see that notation somehow helps to make it more straightforward So, what is dot product?

  但是你会发现，这个方法会让问题更简单，那么，什么是“点积”？

• Under most conditions, the dot product can be ignored, so the assumption of the uniform intensity is rational.

  在大多数应用中，点乘项可以忽略，因此，光强均匀的假设是合理的。

• So, that"s going to be one of the main uses of dot product.

  呃，这就是点乘的一个主要用途。

• The dot-product direction of the light with the vertex.

  点乘每个点光的方向向量。

• Let us take a down-to-earth example of a dot product.

  举一个点积的，现实例子。
