Is there a vector calculus package/functionality in Sage that are similar to other 2M packages?
1- [Vector Analysis Package](http://reference.wolfram.com/mathematica/VectorAnalysis/tutorial/VectorAnalysis.html)
2- [VectorCalculus](http://www.maplesoft.com/support/help/Maple/view.aspx?path=VectorCalculus)
Thanks.Wed, 22 Jun 2011 16:36:44 +0200https://ask.sagemath.org/question/8183/vector-calculus/Answer by Jason Grout for <p>Hello,</p>

https://ask.sagemath.org/question/8183/vector-calculus/?answer=12016#post-id-12016There is also a bunch of work going on in differential geometry which may be of interest: http://www.sagemath.org/doc/reference/tensor.html and http://trac.sagemath.org/sage_trac/ticket/10132. However, if there are things that are not implemented, patches are always welcome!Mon, 04 Jul 2011 21:15:19 +0200https://ask.sagemath.org/question/8183/vector-calculus/?answer=12016#post-id-12016Answer by niles for <p>Hello,</p>

https://ask.sagemath.org/question/8183/vector-calculus/?answer=12460#post-id-12460There is a fair amount of functionality, although I don't know if you'll find what specifically what you want. Here are some suggestions:
* Evaluate `vector?` in a notebook cell or at a `sage:` prompt to see the introductory documentation for vectors in Sage.
* See the reference manual for [Matrices][2]
* Coordinate transformations were included in the [Function Plotting][4] section of the manual (although I find it a little confusing). See e.g. [Spherical][3] coordinate system.
* The section of the reference manual on [Plotting vector fields][5]

https://ask.sagemath.org/question/8183/vector-calculus/?comment=21558#post-id-21558Thanks for the answer. I am particularly interested in Laplacian operator, Spherical coordinate system, and plotting vector fields in various coordinate systems.Wed, 22 Jun 2011 23:47:44 +0200https://ask.sagemath.org/question/8183/vector-calculus/?comment=21558#post-id-21558
