Find the gradient vector field (\vec F (x, y, z)) of f(x, y, z) = x^3y^6z^4. Find the gradient vector field of the following functions: (a) f(x, y, z) = 1 / sqrt(x^2+y^2+z^2) (b) f(x, y) = sin(y^2 - x^2 ) Find the gradient vector field of the foll...
我们接着就要定义gradient,这样我们就能定义Dirichlet energy和laplacian算子。 Gradient vector field: 给定一个流形 M\subseteq R^m 和一个映射 f:M\rightarrow R 。对于任一 p\in M ,都存在一个唯一的 \nabla f(p) \in T_pM 使得\forall v\in T_pM , df_p(v)=v\cdot\nabla f(p) 在平面的...

The term "gradient" is typically used for functions with several inputs and a single output (a scalar field). Yes, you can say a line has a gradient (its slope), but using "gradient" for single-variable functions is unnecessarily confusing. Keep it simple. ...

Triangles used to render 3D objects must more properly be colored with a gradient between the three vertices, but such a gradient is not supported by the interfaces that derive from ID2D1Brush. This means I must dig even deeper into Direct2D and get access to the same shading tools that ...
