directional derivative

directional derivative什么意思,directional derivative翻译

基本解释

na.: 【数】方向导数
网络: 一个函数f的方向导数；方向导函数；方向微分

英汉解释

• 【数学】方向导数

• 定向导数

例句

• The objective function increases in the direction of the directional derivative of the objective function.

  在目标函数延伸的这个方向上，目标函数会逐渐改进。

• A linear programming method by which any directional derivative at any point can be computed is given.

  并给出一个求解任何点处任何方向导数的线性规划方法。

• The directional derivative in a direction that"s perpendicular to the gradient is basically zero.

  垂直于梯度的方向上，方向导数为零。

• So the derivative in any direction, tangent to g equals c, should be the directional derivative of f, in any such direction, should be zero.

  所以这个与g=c相切的导数，应该是f的方向导数，在这个方向下，应该是等于0的。

• So, now, similarly, the directional derivative means, actually, we"ll be slicing our graph by the vertical plane.

  类似地，方向导数的意思是，用垂直平面切开图像。

• Derivatives in higher dimensions, directional derivative and gradient.

  在多维度中的微分、方向导数和梯度。

• And that"s basically, yes, that"s the directional derivative.

  基本上是的，那就是方向导数。

• Use of signal joint probability of directional derivative entropy minimum get the best rotation angle !

  利用信号联合概率的方向导数熵最小获得最佳的旋转角度！

• Well, it"s actually the directional derivative in that direction.

  它其实是那个方向的方向导数。

• And, the slope is going to be the directional derivative in that direction OK, I think that"s as graphicas I can get.

  这个斜率就是此方向的方向导数，好了，我想我说的已经尽量图形化了。
