[Home](./index.md) > [server](./server.md) > [Matrix4](./server.matrix4.md) ## Matrix4 class Represents a 4x4 matrix. **Signature:** ```typescript export default class Matrix4 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 4x4 matrix. Various convenience methods are provided for common matrix operations. ## Constructors <table><thead><tr><th> Constructor </th><th> Modifiers </th><th> Description </th></tr></thead> <tbody><tr><td>
