rowvector

A row vector is a mathematical object that is widely used in various fields such as linear algebra, physics, engineering, and computer science. It is a one-dimensional array or matrix with a single row and multiple columns. Row vectors are typically denoted using a horizontal line of elements enclosed in angle brackets, parentheses, or brackets, such as <a, b, c> or (a, b, c) or [a, b, c].

In linear algebra, row vectors are often used to represent linear transformations, equations, and systems. They can also be used to represent points in space, directions, and other geometric entities. Row vectors can be added, subtracted, and multiplied by scalars, and they can be used to compute the dot product and cross product with other vectors.

Row vectors are closely related to column vectors, which are one-dimensional arrays with a single column and multiple rows. In fact, a row vector can be obtained by transposing a column vector, and vice versa. The transpose of a row vector is a column vector, and the transpose of a column vector is a row vector.

Row vectors are also used in computer science, particularly in graphics and game programming. They are used to represent the position, direction, and orientation of objects in 2D and 3D space. Row vectors are also used in machine learning and data analysis, where they are used to represent data points, features, and observations.

In summary, a row vector is a one-dimensional array with a single row and multiple columns. It is a fundamental mathematical object that is widely used in various fields such as linear algebra, physics, engineering, and computer science. Row vectors can be added, subtracted, and multiplied by scalars, and they can be used to compute the dot product and cross product with other vectors. They are closely related to column vectors and are used in computer graphics, machine learning, and data analysis.
