Comments:
The class MeanNdC serves for computation of the mean of a set of N-dimensional data points. The class is implemented as a bid object able to share memory with points.

private PointNdC

LongIntT number;

The number of points represented by mean object.

MeanNdC(const SizeT dim)

Creates zero mean representing the 'n'-dimensional set containing no data points.

MeanNdC(const PointNdC & point)

Creates the mean vector representing the data set containing just one data point. This object is attached to the memory of 'point'.

MeanNdC(LongIntT n,const PointNdC & mean)

Creates the mean vector representing the data set containing 'n' points and represented by the 'mean'. This object is attached to the memory of 'mean'.

MeanNdC(const MeanNdC & mean)

Copy constructor. In fact it creates only another handler.

const MeanNdC & operator=(const MeanNdC & mean)

Assigment.

MeanNdC Copy() const

Returns a new physical copy of this object. Information about an object ---------------------------

LongIntT Number() const

Returns number of points which were added into the object.

const MeanNdC & MeanNd() const

Access to the const object.

MeanNdC & MeanNd()

Access to the object.

const PointNdC & Mean() const

Returns the current value of the mean. Object modification -------------------

MeanNdC & SetZero()

Total initialization of this object resulting in the representation the empty set of data points.

MeanNdC & Set(LongIntT n,const PointNdC & m)

Sets the new content of mean object. It will represent 'n' points with the mean location 'm'.

MeanNdC & operator+=(const PointNdC & point)

Adds a point to the set.

MeanNdC & operator-=(const PointNdC & point)

Removes a point from the set. Be carefull to remove a point which was already added to the set, otherwise the representation will not describe a real set.

MeanNdC & operator+=(const MeanNdC & mean)

Adds the whole set of points represented by the mean object 'm'.

MeanNdC & operator-=(const MeanNdC & mean)

Removes the whole set of points represented by the mean object 'm'. Be carefull to remove points which was already added to the set, otherwise the representation will not describe a real set.
