## Libraries.Compute.MatrixTransform.Rotation Documentation

This is a MatrixTransform class to rotate a Matrix either left or right. Attribute Returns A new matrix after the operation is performed.

Example Code

``````use Libraries.Compute.Matrix
use Libraries.Compute.MatrixTransform.Rotation

class Main
action Main
Matrix matrix
matrix:Fill(2, 3, 0.0)
matrix:SetColumn(0, 1.1)
matrix:SetColumn(1, 2.1)
matrix:SetColumn(2, 3.1)
Rotation rotation
rotation:Right()
Matrix result = rotation:Transform(matrix)
output result:ToText()
end
e``````

## Summary

### Actions Summary Table

ActionsDescription
Compare(Libraries.Language.Object object)This action compares two object hash codes and returns an integer.
Equals(Libraries.Language.Object object)This action determines if two objects are equal based on their hash code values.
GetHashCode()This action gets the hash code for an object.
Left()This sets the transform operation to rotate left.
Right()This sets the transform operation to rotate right.
Transform(Libraries.Compute.Matrix matrix)This method applies the transform to the Matrix.

## Actions Documentation

### Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

``````Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smalle``````

#### Return

integer: The Compare result, Smaller, Equal, or Larger.

### Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Example Code

``````use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(``````

#### Return

boolean: True if the hash codes are equal and false if they are not equal.

### GetHashCode()

This action gets the hash code for an object.

Example Code

``````Object o
integer hash = o:GetHashCode``````

#### Return

integer: The integer hash code of the object.

### Left()

This sets the transform operation to rotate left.

Example Code

``````use Libraries.Compute.Matrix
use Libraries.Compute.MatrixTransform.Flip

class Main
action Main
Rotation rotation
rotation:Left()
end
e``````

This sets the transform operation to rotate right.

Example Code

``````use Libraries.Compute.Matrix
use Libraries.Compute.MatrixTransform.Flip

class Main
action Main
Rotation rotation
rotation:Right()
end
e``````

### Transform(Libraries.Compute.Matrix matrix)

This method applies the transform to the Matrix. Attribute Parameter The matrix to transform. Attribute Returns A new matrix after the operation is performed.

Example Code

``````use Libraries.Compute.Matrix
use Libraries.Compute.MatrixTransform.Rotation

class Main
action Main
Matrix matrix
matrix:Fill(2, 3, 0.0)
matrix:SetColumn(0, 1.1)
matrix:SetColumn(1, 2.1)
matrix:SetColumn(2, 3.1)
Rotation rotation
rotation:Left()
Matrix result = rotation:Transform(matrix)
output result:ToText()
end
