Comments:
The class Point2dArray1dC represents 1-dimensional array of 2-dimensional points.

public Array1dC<class DataC>

typedef double RealT;

general real parameter.

Point2dArray1dC()

Empty array of points.

Point2dArray1dC(const SizeT n)

Creates an array of 'n' points.

Point2dArray1dC(const char * filename)

Creates an array of points from the input file 'filename'.

Point2dArray1dC(istream & s)

Creates an array of points from the input stream s.

Point2dArray1dC(const Array1dC<Point2dC> & points)

Constructs an array of points from the array (as a big object).

Point2dArray1dC(const Point2dArray1dC & points)

Another access to the array of points.

Mean2dC Mean() const

Returns the mean of the points (e.g. the centroid).

Line2dPPC FitLineXY() const

Returns the line which has the smallest sum of distance squares from points.

RealT SumSqrResiduum(const Line2dPPC & l) const

Returns the sum of squared distances of points from the line 'l'.

void SeparatingLines() const

For each pair of points finds the separating line. All points must be different. NOT IMPLEMENTED.

Array1dC<Point2dC> Copy() const

Creates a new physical copy of the array.

Array1dC<Point2dC> & Copy(const Array1dC<Point2dC> & orig)

Copies values from the 'orig' array into this array.
Only items from the overlapping part of the ranges are copied. The function returns this array.

Array1dC<Point2dC> & Copy(const IndexRangeC & r,const IndexT off)

Copies values from the index range 'r' into the new position with the offset 'off'.
Only those items which original position and destination are inside of the index range of this array are copied.

Array1dC<Point2dC> & Copy(const IndexT off,const Array1dC<Point2dC> & a)

Copies the maximum possible part of array 'a' into this array.
The first element of array 'a' is placed into the element of this array with index 'off'. The functio returns this array.

const Array1dC<Point2dC> & operator=(const Array1dC<Point2dC> & vv)

Assigment, as for a BIG_OBJECT.
Access to the object elements. ------------------------------

const Array1dC<Point2dC> & Array1d() const

Access to the whole array.

Array1dC<Point2dC> & Array1d()

Access to the whole array.

SArray1dC<Point2dC> SArray1d()

Create an access as an sarray.
NB. This does NOT copy the data, it only make a new access to it. If the array does not have contain element '0' an error will occure in check mode, when optimised is enabled an empty array will be returned. In anycase only elements 0 and above will be accessable. Array representation modifications. -----------------------------------

Array1dC<Point2dC> Enlarge(const IntT factor = 2) const

Enlarges the array by item duplications.
Every item is duplicated 'factor' times. The return array is extended by adding of higher indexes.

Array1dC<Point2dC> Extend(const SizeT n) const

Returns the array whose range is extended by adding 'n' items with default value from both limits of the range.
This array value are copied into the same index positions in the returned array.

Array1dC<Point2dC> & Append(const Array1dC<Point2dC> & a)

This array is extended by the length of the array 'a' and the contents of both arrays are copied to it.
The function supports empty arrays. Logical operations. -------------------

BooleanT IsSharing(const Array1dC<Point2dC> & arr) const

Returns TRUE if this array and the array 'arr' are subarrays of the the same array.
Special operations. -------------------

void DebugAddresses() const

Prints addresses into 'cerrAMMA'.

const BodyRefCounterC & RefCounter() const

Returns access to reference counter.

const RangeBufferAccessC<Point2dC> & operator=(Point2dC * bp)

Changes the reference element to the element pointed by 'bp'.
Access to the object --------------------

Point2dC * ReferenceElm(void) const

Returns the pointer to the reference element of the attached buffer. The reference element need not to be the valid element of the buffer.

void * ReferenceVoid(void) const

Returns the pointer to the reference element of the attached buffer. The reference element need not to be the valid element of the buffer. The function is intended to be used in printing.

const BufferAccessC<Point2dC> & Access(void) const

Returns this object.

Point2dC * DataStart()

Returns the address of the first element of the buffer..

const Point2dC * DataStart() const

Returns the address of the first element of the buffer..

SizeT N() const

Returns the number of elements of the array.

SizeT Size() const

Returns the number of elements of the array.

const IndexRangeC & Limits() const

Returns the usable range of indeces expressed by this object.

const IndexRangeC & Range() const

Returns the usable range of indeces expressed by this object.

IndexT IMin() const

Returns the minimum index of the range of this access.

IndexT IMax() const

Returns the maximum index of the range of this access.

const Point2dC & operator[](const IndexT i) const

Read-only access to the ('i'+1)-th element of the buffer.

Point2dC & operator[](const IndexT i)

Read-write access to the ('i'+1)-th element of the buffer.

const RangeBufferAccessC<Point2dC> & RAccess(void) const

Returns this object. Logical functions -----------------

BooleanT IsValid() const

Returns TRUE if this buffer access is not a default access object.

BooleanT IsEmpty() const

Returns TRUE if the size of the array is zero.

BooleanT Contains(const IndexT i) const

Returns TRUE if the array contains an item with the index 'i'.

BooleanT IsOverlapping(const RangeBufferAccessC<Point2dC> & acc) const

Returns TRUE if this access has an item with the same index as an item of the access 'acc'. Modifications of the access ---------------------------

const RangeBufferAccessC<Point2dC> & operator+=(const SizeT i)

Changes indeces of the access to be 'i' units higher.

RangeBufferAccessC<Point2dC> operator+(const SizeT i) const

Creates the new access object with the indeces 'i' units higher than those used in this access object.

const IndexRangeC & ShrinkHigh(const SizeT k)

Changes the number of elements by subtracting the last 'k' elements.

void ShiftIndexes(const IndexT offset)

All indexes of the items will be changed by 'offset'.
The range will be shifted by -offset.

void SetSubRange(const IndexT newMin,const IndexT newMax)
