CombinationWithRepetition()

list< vector< int > > Gedim::Utilities::CombinationWithRepetition ( int  n, int  k  )

static

create Combination With Repetition with n elements in k subset

Parameters

n	size of elements
k	size of subset

RandomArrayNoRepetition()

std::vector< unsigned int > Gedim::Utilities::RandomArrayNoRepetition ( const unsigned int &  n, const unsigned int &  maxNumber = RAND_MAX, const unsigned int &  seed = time(nullptr)  )

static

Parameters

n	size of elements
seed	the side

Returns

random array

RandomSeed()

static unsigned int Gedim::Utilities::RandomSeed ( )

inlinestatic

Shuffle()

template<class container >

static void Gedim::Utilities::Shuffle ( container &  array, const unsigned int &  seed = time(nullptr)  )

inlinestatic

Shuffle an array.

Slope()

template<typename _InputIterator >

static double Gedim::Utilities::Slope ( _InputIterator  x_begin, _InputIterator  y_begin, const unsigned int &  n  )

inlinestatic

Compute the regression line slope of points (x,y).

Parameters

x_begin	Start of x range.
y_begin	Start of y range.
n	the number of points

Returns

The slope.

SortArrayIndices()

template<typename T >

static std::vector< unsigned int > Gedim::Utilities::SortArrayIndices ( const std::vector< T > &  array )

inlinestatic

Gives you back the array sorted indices.

Parameters

array

the array to sort

Returns

the indices of the array ordered

Union()

template<typename T >

static T Gedim::Utilities::Union ( const std::initializer_list< T > &  arrays )

inlinestatic

Unused()

template<class T >

static void Gedim::Utilities::Unused ( const T &  )

inlinestatic
