## NAME

Vector

## SYNOPSIS

use Vector;

use Vector qw(:all);

## DESCRIPTION

Vector class provides the following methods:

new, AddValues, Copy, GetLength, GetMagnitude, GetNumOfNonZeroValues , GetPercentOfNonZeroValues, GetSize, GetValue, GetValues, GetX, GetXYZ, GetY , GetZ, IsVector, Normalize, SetValue, SetValuePrintFormat , SetX, SetXYZ, SetY, SetZ, StringifyVector, IsVector

The following functions are available:

IsVector, SetValuePrintFormat UnitXVector, UnitYVector, UnitZVector, UnitVector, ZeroVector

The following operators are overloaded:

"" 0+ bool
@{}
+ - * / %
x .
== != < <= > >=
neg
abs exp log sqrt cos sin

## FUNCTIONS

new
  $NewVector = new Vector();
  $NewVector = new Vector(@Values);
  $NewVector = new Vector(\@Values);
  $NewVector = new Vector($AnotherVector);

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

AddValues
  $Vector->AddValues(@Values);
  $Vector->AddValues(\@Values);
  $Vector->AddValues($AnotherVector);

  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
  $Vector->SetXYZ(@Values);
  $Vector->SetXYZ(\@Values);
  $Vector->SetXYZ($AnotherVector);

  Sets XYZ values of a 3D vector and returns Vector.

SetY
  $Vector->SetY($Value);

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

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();

  Returns a 3D UnitXVector.

UnitYVector
  $UnitYVector = UnitYVector();

  Returns a 3D UnitYVector.

UnitZVector
  $UnitZVector = UnitZVector();

  Returns a 3D UnitZVector.

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

  Returns a ZeroVector of Size. Default size: 3.
