Class for manipulating vector of real numbers

vect()

Constructor. Dummy constructor initialized to the zero-dimensional vector

vect(int n, double val = 0.0)

Constructor. The vector is initialized to the dimension n. All its elements are initialized to zero

Parameters:

- n vector dimension

vect(double* array, int n)

Constructor. The vector is initialized using the array of double array.

Parameters:

array - array of double
- n vector dimension

vect(const vect&)

Copy Constructor

~vect()

Destructor

vect& operator=(const vect&)

Overloading assignment operator

int dim() const

Returns the dimension of the vector.

Returns:

dimension of the vector

double& operator[](int i)

Index overloading.
It returns the i-th componenet of the vector.

Parameters:

i - i-th component of the vector

Returns:

value of i-th component of the vector

double operator[](int) const

Index overloading.
It returns the i-th componenet of the vector.

Parameters:

i - i-th component of the vector

Returns:

value of i-th component of the vector

double sqr_length() const

Returns the square of the Euclidean length of the vector.

Returns:

square of the Euclidean length of the vector

double length() const

Returns the Euclidean length of the vector.

Returns:

Euclidean length of the vector

vect norm() const

Returns the vector normalized.

vect& operator+=(const vect&)

Overloading += operator

vect& operator-=(const vect&)

Overloading -= operator

vect operator+(const vect& v1) const

Overloading addition

vect operator-(const vect& v1) const
