In mathematics, specifically multilinear algebra, a dyadic or dyadic tensor is a second order tensor, written in a notation that fits in with vector algebra. There are numerous ways to multiply two Euclidean vectors. The dot product takes in two vectors and returns a scalar, while the cross product returns a pseudovector. … See more 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 … See more Vector projection and rejection A nonzero vector a can always be split into two perpendicular components, one parallel (‖) to the direction of a unit vector n, and one … See more • Kronecker product • Bivector • Polyadic algebra • Unit vector • Multivector • Differential form See more Product of dyadic and vector There are four operations defined on a vector and dyadic, constructed from the products defined on … See more There exists a unit dyadic, denoted by I, such that, for any vector a, $${\displaystyle \mathbf {I} \cdot \mathbf {a} =\mathbf {a} \cdot \mathbf {I} =\mathbf {a} }$$ See more Some authors generalize from the term dyadic to related terms triadic, tetradic and polyadic.
