BUILT-IN MATHEMATICA SYMBOL
TensorExpand
TensorExpand[texpr]
expands out tensor-related products in the symbolic tensor expression texpr.
- TensorExpand expands sums and products by scalars in tensorial arguments.
- Expressions involving Dot and Cross are expanded by converting products of pairs of Cross subexpressions into linear combinations of Dot products.
- Symbolic arguments of Cross are assumed to represent vectors of adequate dimensionality.
- Symbolic arguments of MatrixPower and Inverse are assumed to represent invertible square matrices.
Tensor products of linear combinations are not expanded automatically:
| Out[1]= |  |
Expand the product:
| Out[2]= |  |
Expand a scalar product of two cross products:
| Out[1]= |  |
