Public Methods

Vector()

Constructor with no arguments (must subsequently invoke "alloc" to allocate memory)

Vector(size_type n)

Constructor: create vector of "n" elements.

Vector(size_type n, const T &e)

Constructor: create vector of "n" elements "e".

Vector(const Vector<T> &)

Copy constructor: elements are copied into a new vector.

Vector<T> & operator=(const T f)

Assignment operator: set all elements to "f".

Vector<T> & operator+=(const T f)

Add the value "f" to every element of the vector.

Vector<T> & operator-=(const T f)

Subtract the value "f" to every element of the vector.

Vector<T> & operator*=(const T f)

Uniform grid generation.

void range(const T imin=0)

Uniform grid generation with unit increment.

void random(void)

Fill the vector with random numbers between 0 and 1 (two subsequent calls to random will generate different elements)

size_t bra(const T elem)

Return the index of the element closest to the left of/at position of elem.

Vector<size_t> bra(const Vector<T> &elem)

Return the indices of the elements that are closest to the left of elem.

Return reference to "i"-th element.

inline T& operator()(size_type i)

Returns reference to an element of index "i" (can be used for assignment).

Documentation

The vector class

The class to represent vectors. Elements are adjacent in memory.

Vector()

Constructor with no arguments (must subsequently invoke "alloc" to allocate memory)

Vector(size_type n)

Constructor: create vector of "n" elements.

Parameters:

n - vector size

Vector(size_type n, const T &e)

Constructor: create vector of "n" elements "e".

Parameters:

n - vector size
e - value of each element

Vector(const Vector<T> &)

Copy constructor: elements are copied into a new vector.

Parameters:

vector - to be copied

Vector<T> & operator=(const T f)

Assignment operator: set all elements to "f".

Parameters:

f - scalar

Returns:

vector instance

Vector<T> & operator+=(const T f)

Add the value "f" to every element of the vector.

Parameters:

f - scalar

Returns:

vector

Vector<T> & operator-=(const T f)

Subtract the value "f" to every element of the vector.

Parameters:

f - scalar

Returns:

vector

Vector<T> & operator*=(const T f)

Multiply every element by the value "f".

Parameters:

f - scalar

Returns:

vector

Vector<T> & operator/=(const T f)

Divide every element by the value "f".

Parameters:

f - scalar

Returns:

vector

Vector<T> & operator+=(const Vector<T> &w)

Vector addition.

Parameters:

w - vector

Returns:

vector = original vector incremented by w

Vector<T> & operator-=(const Vector<T> &w)

Vector subtraction.

Parameters:

w - vector

Returns:

vector = original vector decremented by w

Vector<T> & operator*=(const Vector<T> &w)

Elementwise multiplication. Multiply every vector element (of the vector on the left of "*=") by its counterpart in the "b" vector.

Parameters:

w - vector

Returns:

vector

Vector<T> & operator/=(const Vector<T> &w)

Elementwise division. Divide every vector element (of the vector on the left of "*=") by its counterpart in the "b" vector.

Parameters:

w - vector

Returns:

vector

void space(const T xmin, const T xmax)

Uniform grid generation. Elements are set so as to span uniformly from xmin to xmax, in increasing order.

Parameters:

- xmin minimum value
- xmax maximum value

void range(const T imin=0)

Uniform grid generation with unit increment. Similar to space except that the increment is one. For instance x.range(0) has elements 0, 1, ... (up to size x.size()-1).

space

void random(void)

Fill the vector with random numbers between 0 and 1 (two subsequent calls to random will generate different elements)

size_t bra(const T elem)

Return the index of the element closest to the left of/at position of elem. This assumes that the sequence is monotonically increasing. The min/max return values are 0 and size()-1, respectively.

Parameters:

elem - reference abscissa

See Also:

ket

Vector<size_t> bra(const Vector<T> &elem)

Return the indices of the elements that are closest to the left of elem. This assumes that the sequence is monotonically increasing.

Parameters:

elem - reference abscissa

size_t ket(const T elem)

Return the index of the element closest to the right of elem. This assumes that the sequence is monotonically increasing. The min/max return values are 0 and size()-1, respectively.

Parameters:

elem - reference abscissa

See Also:

bra

Vector<size_t> ket(const Vector<T> &elem)

Return the indices of the elements that are closest to the right of elem. This assumes that the sequence is monotonically increasing.

Parameters:

elem - reference abscissa

Vector<T> & alloc(const size_type n)

Resizes the vector to the "n" size.

Parameters:

element

inline T& operator()(size_type i)

Returns reference to an element of index "i" (can be used for assignment).

Parameters:

i - index

Returns:

element
