Topic: Row vector


  
  Row vector - Wikipedia, the free encyclopedia
In linear algebra, a row vector is a 1 × n matrix, that is, a matrix consisting of a single row:
The transpose of a row vector is a column vector.
The set of all row vectors forms a vector space which is the dual space to the set of all column vectors.

 1.1 The graph list data structure
Row vector of the y coordinates of the nodes.
Row vector of the sizes of the node diameters in pixels (a node is drawn as a circle).
Row vector of the sizes of the font used to draw the name or the label of the node; you can choose 8, 10, 12, 14, 18 or 24.

The symbol for a vector is a lower case letter in bold print Column vector: a =  EMBED Equation.3  Row vector: a’ = (2, 3, 1) Small letter with a prime.
The vector a’ is the transpose of a, that is, we have changed from a column to a row.
Matrices are conformable when the number of elements in the rows (number of columns) of the first matrix equals the number of elements in the columns (number of rows) of the second matrix.

The additive operations of the vector must thus be compatible with that for lists, implying that the list entries are the coefficients of the vector with respect to some basis.
Because row vectors are just a special case of lists, all operations and functions for lists are applicable to row vectors as well (see Chapter Lists).
The rules for arithmetic operations involving row vectors are in fact special cases of those for the arithmetic of lists, as given in Section Arithmetic for Lists and the following sections, here we reiterate that definition, in the language of vectors.

 [ref] 21 Row Vectors   (Site not responding. Last check: 2007-09-17)
To avoid this a list that is a row vector may, but need not, have an internal flag set that tells the operations that this list is indeed a row vector.
The results of vector operations, i.e., binary operations that involve vectors, are known by construction to be vectors, and thus have the flag set upon creation.
However if the vector is a vector over a finite field and you assign an element from the same finite field the vector will keep its flag.

 2D and Beyond!   (Site not responding. Last check: 2007-09-17)
When you use two levels of iterators (here via the nested loops) on a 2D vector structure, you have an individual element which is an individual memory location of the overall base type.
This means the rows will end when two sentinels in a row (pardon the pun) are detected.
Since during processing we ask each row for its begin() and end() individually, this will cause no problems later in the code.

Suppose you have a matrix "A" and a vector "b" and you want to find out a vector "x" so that C, i.e., the vector "x" which solves the equation system represented by the matrix "A" and the vector "b".
Using Gaussian transformations (multiplying a row or column with a factor, swapping two rows or two columns and adding a multiple of one row or column to another), it is possible to decompose any matrix "A" into two triangular matrices, called "L" and "R" (for "Left" and "Right").
Provided none of the two input vectors is the null vector, then the two vectors are orthogonal, i.e., have an angle of 90 degrees between them, exactly when their scalar product is zero, and vice-versa.
