**Row equivalence**— In linear algebra, two matrices are row equivalent if one can be changed to the other by a sequence of elementary row operations. Alternatively, two m times; n matrices are row equivalent if and only if they have the same row space. The concept… …102

**Row space**— In linear algebra, the row space of a matrix is the set of all possible linear combinations of its row vectors. The row space of an m times; n matrix is a subspace of n dimensional Euclidean space. The dimension of the row space is called the… …103

**Row echelon form**— In linear algebra a matrix is in row echelon form if * All nonzero rows are above any rows of all zeroes, and * The leading coefficient of a row is always strictly to the right of the leading coefficient of the row above it.This is the definition …104

**Row (database)**— In the context of a relational database, a row also called a record or tuple represents a single, implicitly structured data item in a table. In simple terms, a database table can be thought of as consisting of rows and columns or fields. Each… …105

**Row-major order**— In computing, row major order and column major order describe methods for storing multidimensional arrays in linear memory. Following standard matrix notation, rows are numbered by the first index of a two dimensional array and columns by the… …106

**Row and column spaces**— The row space of an m by n matrix with real entries is the subspace of R n generated by the row vectors of the matrix. Its dimension is equal to the rank of the matrix and is at most min( m , n ).The column space of an m by n matrix with real… …109

**Row vector**— In linear algebra, a row vector or row matrix is a 1 times; n matrix, that is, a matrix consisting of a single row: [harvtxt|Meyer|2000, p. 8] :mathbf x = egin{bmatrix} x 1 x 2 dots x m end{bmatrix}.The transpose of a row vector is a column… …110

**Row Address Strobe**— Dieser Artikel beschreibt den DRAM Chip. Für das mit diesen Chips aufgebaute DRAM Modul (ugs.: Speicherriegel), siehe Artikel Speichermodul. Dynamic Random Access Memory (DRAM), oder der halb eingedeutschte Begriff Dynamisches RAM, bezeichnet… …
