Public constructors
`<init>(values: FloatArray = floatArrayOf( 1f, 0f, 0f, 0f, 0f, 1f, 0f, 0f, 0f, 0f, 1f, 0f, 0f, 0f, 0f, 1f ))`

Public methods
operator Float	`get(row: Int, column: Int)`
Unit	`invert()` Invert `this` Matrix.
Offset	`map(point: Offset)` Does the 3D transform on point and returns the `x` and `y` values in an Offset.
Rect	`map(rect: Rect)` Does a 3D transform on rect and returns its bounds after the transform.
Unit	`map(rect: MutableRect)` Does a 3D transform on rect, transforming rect with the results.
Unit	`reset()` Resets the `this` to the identity matrix.
Unit	`rotateX(degrees: Float)` Applies a degrees rotation around X to `this`.
Unit	`rotateY(degrees: Float)` Applies a degrees rotation around Y to `this`.
Unit	`rotateZ(degrees: Float)` Applies a degrees rotation around Z to `this`.
Unit	`scale(x: Float = 1f, y: Float = 1f, z: Float = 1f)` Scale this matrix by x, y, z
operator Unit	`set(row: Int, column: Int, v: Float)`
Unit	`setFrom(matrix: Matrix)` Sets the entire matrix to the matrix in matrix.
operator Unit	`timesAssign(m: Matrix)` Multiply this matrix by m and assign the result to this matrix.
String	`toString()`
Unit	`translate(x: Float = 0f, y: Float = 0f, z: Float = 0f)` Translate this matrix by x, y, z

Extension functions

Boolean	`Matrix.isIdentity()` Whether the given matrix is the identity matrix.
Unit	`Matrix.setFrom(matrix: Matrix)` Set the matrix values the native android.graphics.Matrix.
