Detailed Description

template<typename value_t>
class nabla::vector< value_t >

Vector template class.

This class represents a vector, i.e. a string of values.

Object of this type is a column vector – can act as a v.size() by 1 matrix. (For more information on orientation see Vector Orientation.)

Additional guarantees:: Elements are stored in memory continuously. This implies
&v(i)==&v(0) + i
is always satisfied for non-empty vector and i<v.size().

Constructor & Destructor Documentation

vector ( )

inline

Default constructor.

Initializes empty vector, i.e. zero sized vector with no elements.

Member Function Documentation

void assign ( const vector_expression< value_type, expr_t, tag > & rhs )

inline

Assigns vector expression to this object.

Warning: This function may produce suprising results. Equivalent effect of this function is if this object were erased and then assigned the rhs.

This function assigns rhs in the most efficient way. That means that no temporary is introduced to store intermediate result. This circumstance can cause suprising results as stated above.

Like in the STL this function doesn't care about object's previous state. The function discards all the contents (which may immediately invalidate all references to this object) and copies the result of rhs expression to this object's new contents.

In other words this object should not be involved in the argument expression rhs. Otherwise this function may produce unexpected result or even crash the program.

void resize ( size_t size )

inline

Resizes vector.

Changes vector size to size. Values of elements are undefined.
