[Home](./index.md) > [server](./server.md) > [Matrix2](./server.matrix2.md) ## Matrix2 class Represents a 2x2 matrix. **Signature:** ```typescript export default class Matrix2 extends Float32Array ``` **Extends:** Float32Array ## Remarks All matrix methods result in mutation of the matrix instance. This class extends `Float32Array` to provide an efficient way to create and manipulate a 2x2 matrix. Various convenience methods are provided for common matrix operations. ## Constructors
