matrix<T, Row>
Defined in header file:  matrix.hh

Description

A matrix is a ...

Example

    matrix<int> m(3, 2, 100);
    m[2][1] = 9;
    m[1][0] = m[2][1] + m[1][1];
    assert((m[1][0] == 109));
    cout << m << endl;

The result that is written to stdout is:

[[100 100]
 [109 100]
 [100 9]
]
  

Public base classes

Template parameters

Parameter	Description	Default
T	The value_type of the matrix, i.e. the type of the stored elements.
Row	The type of a row.	unbounded_vector<T>

Constructors

Constructor	Description
matrix()	Creates an empty matrix.
matrix(const matrix& m)	Copy constructor.
matrix(size_type n)	Creates a matrix with n empty rows.
matrix(size_type rows, size_type cols)	Creates a matrix with _rows_ rows and _cols_ cols.
matrix(rows, cols, T())	Creates a matrix with _rows_ rows and _cols_ cols. Each element is a copy of _t_.
matrix(size_type rows, size_type cols, const T& t)

Members

Types	Description
value_type	The type (T) of the objects stored in the matrix.
pointer_type	Pointer to T.
reference	Reference to T.
const_reference	Const reference to T.
size_type	An unsigned integral type.
difference_type	A signed integral type.
row_type	The type (Row) of a row.
iterator	An iterator to iterate through the rows.
const_iterator	Const iterator.
reverse_iterator	An iterator to iterate backwards through the rows.
const_reverse_iterator	Const backward iterator.
Methods
row_type&  operator[](size_type n)	Returns a reference to the given row.
const row_type&  operator[](size_type n)   const	Returns a const reference to the given row.
void  push_back(const row_type& row)	Inserts a new row at the end.
void  pop_back()	Removes the last row.
size_type  size()   const	Returns the number of rows.
size_type  max_size()   const	Returns the maximum number of rows.
bool  empty()   const	Returns true if the matrix contains no rows.
