curl是什么呢，是一个旋转，你就当它是一个漩涡，漩涡的旋转使得吸进来的水等于排出去的水，所以它的div就是0.

A straightforward example of this formula is the carrying of the internal equilibrium equations from the deformed configuration to the reference one. The second identity, which deals with the curl of a product of the transposed of a linear mapping and another one, leads to a very simple ...
The divergence of a vector field in space Example Find the divergence and the curl of F = 2xyz, −xy, −z 2 . Solution: Recall: div F = ∂ x F x +∂ y F y +∂ z F z . ∂ x F x = 2yz, ∂ y F y = −x, ∂ z F z = −2z. Therefore · F =...
Answer to: Find the curl and divergence of the vector field F(x, y, z) = i + (x + yz) j + (xy - 9 \sqrt z) k By signing up, you'll get...
The curl of a vector field is defined as the cross product between the nabla or del operator and the vector field itself. On the other hand, the divergence of a vector field is the dot product of the del operator and the vector field. Answer and Expla...

Find the divergence and the curl of the vector field: {eq}\vec{F}(x, y, z) = x^2y\vec i + 2y^3z\vec j + 3z \vec k {/eq}. Divergence and Curl of a Vector Field: Using the nabla operator we can define the divergence and curl o...
Keras is a minimalist, highly modular neural networks library, written in Python and capable of running on top of either TensorFlow or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing ...
I have got a matrix (let's call it M, M=100x100). I am trying to obtain both divergence and curl. So far, I managed to obtain the divergence of the vector field (which seem correct), by the following steps: ThemeCopy [FX,FY] = gradient(M); div = divergence(FX,FY); Now, I...
