The resulting solution is known as the gradient .
合成解就是通常的梯度风。
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。
In the same way as the gradient, you can add the RG su_x to your macro to access the reconstruction gradient (RG) vector and components of a variable quantity.
读写改造过的梯度矢量和其分量和梯度一样的方式,你可以通过加rg的下标在你的宏中来得到梯度向量和其分量。
