In computer graphics, swizzles are a class of operations that transform vectors by rearranging components. [1] Swizzles can also project from a vector of one dimensionality to a vector of another dimensionality, such as taking a three-dimensional vector and creating a two-dimensional or five-dimensional vector using components from the original vector. [2]
With row-major matrix order, it is easy to transform vectors using dot product operations, since the coefficients of each component are sequential in memory. Consequently, this layout may be desirable if a processor supports dot product operations natively.
It is then possible to implement column-wise lexicographic ordering in order to convert the modified matrices into vectors, ″ and ″. In order to minimize the number of unimportant samples in each vector, each vector is truncated after the last sample in the original matrices X {\displaystyle X} and Y {\displaystyle Y} respectively.
2D computer graphics is the computer-based generation of digital images—mostly from two ... the product of translation matrices is given by adding the vectors:

In C++ several linear algebra libraries exploit the language's ability to overload operators. In some cases a very terse abstraction in those languages is explicitly influenced by the array programming paradigm, as the NumPy extension library to Python , Armadillo and Blitz++ libraries do.
In linear algebra, the outer product of two coordinate vectors is the matrix whose entries are all products of an element in the first vector with an element in the second vector. If the two coordinate vectors have dimensions n and m, then their outer product is an n × m matrix.
