unit vector

单词unit vector

基本解释

un.: 单位矢量；单位向量
网络: 单位失量；矢量称为；当量齿轮

英汉解释

• 单位向量

• 单位矢量

例句

• Sorry, first of all in case you wonder what this is all about, b so let"s say the components of our unit vector are two numbers, a and b.

  首先，以防你们不知道这些是什么，给出这个单位向量的2个分量，a和。

• Draw these segments; then, for each segment, draw the same set of line segments transformed to use that segment as the unit vector.

  绘制这些区段之后，绘制同一套变形线条，用这个区段作为单位向量。

• Then the normal unit vector might be this guy, N in which case indeed three times little n will be big n.

  那么单位法向量可能是这个，在这种情况下，3*n就是。

• OK, so if I give you a unit vector, you can ask yourself, if I move in the direction, how quickly will my function change?

  也就是，如果我给你一个单位向量，试问，我沿着这个方向移动，我的函数值会变化得多快呢？

• And so that means that any vector u, any unit vector tangent to the level set of g is going to be perpendicular to the gradient of f.

  也就是说，任何向量u，任何与g的水平集相切的单位向量，应该要与f的梯度垂直。

• It has two terms: k1 times v-- this is the speed, - this is always positive-- and this is the unit vector of the velocity.

  它有两项：k1*v-，这是速度，总是正的-，这是速度的，单位向量。

• H dotted with a unit vector gives the slope of the hill in the direction of the vector.

  H的梯度点积一个单位向量给出了表面在该向量的方向上的斜率。这称为方向导数。

• DIV as a pixel the smallest unit vector graphics, so draw out the graph has the speed, small footprint advantages.

  以一个像素的DIV作为矢量图形的最小单位，所以绘制出来的图形具有速度快，占用空间小的优势。

• A unit vector in the direction of the projection of normal to T .

  沿着方向上的单位向量，与T垂直。

• If the norm is 1, you have a so-called unit quaternion (just as you would have a unit vector).

  假如平均值为1，你就得到所谓的单位四元数（正象单位矢量）。
