ScalarTripleProduct
As of Version 9.0, vector analysis functionality is built into the Wolfram Language »
ScalarTripleProduct[v1,v2,v3]
gives the scalar triple product of the three 3-vectors v1, v2, and v3 in the default coordinate system.
ScalarTripleProduct[v1,v2,v3,coordsys]
gives the scalar triple product of v1, v2, and v3 in the coordinate system coordsys.
更多信息和选项
- To use ScalarTripleProduct, you first need to load the Vector Analysis Package using Needs["VectorAnalysis`"].
- ScalarTripleProduct[v1,v2,v3,coordsys] is computed by converting v1, v2, and v3 to Cartesian coordinates and then forming the scalar triple product.
