An HTML document is composed of a tree of simple HTML nodes, such as text nodes, and HTML elements, which add semantics and formatting to parts of a document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content ...
The transpose (indicated by T) of any row vector is a column vector, and the transpose of any column vector is a row vector: […] = [] and [] = […]. The set of all row vectors with n entries in a given field (such as the real numbers ) forms an n -dimensional vector space ; similarly, the set of all column vectors with m entries forms an m ...
Column contrast refers to the overall color or greyness established by the column, and can be adjusted in a number of ways. One way is to adjust the relationship between the width and height of the column. Another way is to make adjustments to the typeface, from choosing a specific font, to adjusting weight, style, size and leading. Column ...
It is often denoted Hom(V, k), [2] or, when the field k is understood, ; [3] other notations are also used, such as ′, [4] [5] # or . [2] When vectors are represented by column vectors (as is common when a basis is fixed), then linear functionals are represented as row vectors, and their values on specific vectors are given by matrix products ...
The column space of this matrix is the vector space spanned by the column vectors. In linear algebra, the column space (also called the range or image) of a matrix A is the span (set of all possible linear combinations) of its column vectors. The column space of a matrix is the image or range of the corresponding matrix transformation.
Vector subtraction is performed by adding the scalar multiple of −1 with the second vector operand to the first vector operand. This can be represented by the use of the minus sign as an operator. The difference between two vectors u and v can be represented in either of the following fashions: +
A vector treated as an array of numbers by writing as a row vector or column vector (whichever is used depends on convenience or context): = (), = Index notation allows indication of the elements of the array by simply writing a i, where the index i is known to run from 1 to n, because of n-dimensions.

Boldface is often applied to the first occurrence of the article's title word or phrase in the lead.This is also done at the first occurrence of a term (commonly a synonym in the lead) that redirects to the article or one of its subsections, whether the term appears in the lead or not (see § Other uses, below).
