tensor contraction造句

where on each side, tensor contraction occurs for at least one index.
where the dots indicate tensor contraction and we have used the Einstein summation convention.
This manner of representing tensor contractions by repeated indices is formally similar to the Einstein summation convention.
Synthesizing program F involves projecting UW of unneeded columns and rows, and aggregating ( a . k . a . tensor contraction ):
When vectors and tensors are written without reference to components, and indices are not used, sometimes a dot ?is placed where summations over indices ( known as tensor contractions ) are taken.
It's difficult to find tensor contraction in a sentence. 用tensor contraction造句挺难的

I don't know if there is a simple K-G like equation for spin-1 particles ( photon, gluon ) or if the field tensor contraction as in the Lagrangians simply covers that?
where R _ { \ mu \ nu } is the Ricci tensor, R is the Ricci scalar ( the tensor contraction of the Ricci tensor ), g _ { \ mu \ nu } \, the metric tensor, and G is the universal gravitational constant.
The "'Tensor Contraction Engine "'( TCE ) transforms tensor summation expressions to low level code ( C / Fortran ) for specific hardware being mindful of memory availability, communication costs, loop fusion and ordering, etc . . . . It is used primarily in computational chemistry.
A tensor contraction ( or trace ) between two tensors is represented by the repetition of an index label, where one label is contravariant ( an " upper index " corresponding to a tensor in " V " ) and one label is covariant ( a " lower index " corresponding to a tensor in " V " " ).
