# DOMMatrix

* * **This is an experimental technology**

Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

The

interface represents 4x4 matrices, suitable for 2D and 3D operations.**DOMMatrix**

A 4x4 matrix is suitable to describe any rotation and translation in 3D.

This interface should be available inside Web workers, though some implementations don't allow it yet.

## Properties

*This interface inherits properties from DOMMatrixReadOnly, though some are modified not to be read-only.*

## Methods

*This interface inherits methods from DOMMatrixReadOnly.*

`DOMMatrixReadOnly.multiplySelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being multiplied by the given`DOMMatrix`

. `DOMMatrixReadOnly.preMultiplySelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the given`DOMMatrix`

being multiplied by the original matrix. `DOMMatrix.translateSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix being translated by the given vector. `DOMMatrix.scaleSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix x and y dimensions being scaled by the given factor, centered on the origin given. `DOMMatrix.scale3dSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix x, y and z dimension being scaled by the given factor, centered on the origin given. `DOMMatrix.scaleNonUniformSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix x, y and z dimension being scaled by the given factor for each dimension, centered on the origin given. `DOMMatrix.rotateSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being rotated by the given angle, with the rotation centered on the origin given. `DOMMatrix.rotateFromVectorSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being rotated by the angle between the given vector and (1,0), centered on the origin given. `DOMMatrix.rotateAxisAngleSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being rotated by the given angle and the give vector. `DOMMatrix.skewXSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being skewed along the x-axis by the given factor. `DOMMatrix.skewYSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being skewed along the y-axis by the given factor. `DOMMatrix.invertSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being inverted. If the matrix cannot be inverted, all its components are set to`NaN`

and`is2D()`

returns`false`

. `DOMMatrix.setMatrixValue()`

- Returns itself, a
`DOMMatrix`

, with its describing the matrix representing the same transformation as the CSS`transform`

functions given in parameter.
