Tensor Operations: Contractions, Inner Products, Outer Products
WebCalculate the dot product of A and B. C = dot (A,B) C = 1.0000 - 5.0000i. The result is a complex scalar since A and B are complex. In general, the dot product of two complex vectors is also complex. An exception is when you take the dot product of a complex vector with itself. Find the inner product of A with itself. Web24 Mar 2024 · The contraction operation is invariant under coordinate changes since. and must therefore be a scalar . When is interpreted as a matrix, the contraction is the same … WebDefinitions and terminology Dyadic, outer, and tensor products. A dyad is a tensor of order two and rank one, and is the dyadic product of two vectors (complex vectors in general), whereas a dyadic is a general tensor of order two (which may be full rank or not).. There are several equivalent terms and notations for this product: the dyadic product of two vectors … dedicationes indra
