  FUNCTIONS

        Creates a new Vector object containing *Values* and returns
        NewVector object. In case no *Values* are specified, an empty Vector
        is created.

        Adds values to *Vector* using an array, reference to an array or
        another vector and returns *Vector*.

    Copy
            $NewVector = $Vector->Copy();

        Creates a copy of *Vector* and returns *NewVector*.

    GetLength
            $Length = $Vector->GetLength();

        Returns *Lengh* of a 3D *Vector* corresponding to its dot product.

    GetMagnitude
            $Length = $Vector->GetMagnitude();

        Returns *Lengh* of a 3D *Vector* corresponding to its dot product.

    GetNumOfNonZeroValues
            $Value = $Vector->GetNumOfNonZeroValues();

        Returns number of non-zero values in *Vector*.

    GetPercentOfNonZeroValues
            $Value = $Vector->GetPercentOfNonZeroValues();

        Returns percent of non-zero values in *Vector*.

    GetSize
            $Size = $Vector->GetSize();

        Returns size of a *Vector* corresponding to number of its values.

    GetValue
            $Value = $Vector->GetValues($Index);

        Returns vector Value specified using *Index* starting at 0.

    GetValues
            @Values = $Vector->GetValues();
            $ValuesRef = $Vector->GetValues();

        Returns an array or a reference to an array containing all *Vector*
        values.

    GetX
            $X = $Vector->GetX();

        Returns X value of a 3D *Vector*

    GetXYZ
            @XYZValues = $Vector->GetXYZ();
            $XYZValuesRef = $Vector->GetXYZ();

        Returns XYZ values of a 3D *Vector* as an array or a reference to an
        array containing the values.

    GetY
            $Y = $Vector->GetY();

        Returns Y value of a 3D *Vector*.

    GetZ
            $Z = $Vector->GetZ();

        Returns Z value of a 3D *Vector*.

    IsVector
            $Status = Vector::IsVector($Object);

        Returns 1 or 0 based on whether *Object* is a Vector object.

    Normalize
            $Vector->Normalize();

        Normalizes a 3D *Vector* by dividing its values by the length and
        returns *Vector*.

    SetValue
            $Vector->SetValue($Index, $Value);

        Sets a *Vector* value specified by *Index* to *Value* and returns
        *Vector*.

    SetValuePrintFormat
            $Vector->SetValuePrintFormat($ValuePrintFormat);
            Vector::SetValuePrintFormat($ValuePrintFormat);

        Sets format for printing vector values for a specified *Vector* or
        the whole class. Default format: *%g*.

    SetX
            $Vector->SetX($Value);

        Sets X value of a 3D vector to *Value* and returns *Vector*.

    SetXYZ

    SetZ
            $Vector->SetZ($Value);

        Sets Z value of a 3D vector to *Value* and returns *Vector*.

    StringifyVector
            $String = $Vector->StringifyVector();

        Returns a string containing information about *Vector* object.

    UnitVector
            $UnitVector = UnitVector([$Size]);
            $UnitVector = Vector::UnitVector([$Size]);

        Returns a UnitVector of *Size*. Default size: *3*.

    UnitXVector
            $UnitXVector = UnitXVector();
