math.mat4.normsq

math.mat4.normsq¶

Summary¶

math.mat4.normsq returns the squared Frobenius norm of a 4x4 matrix: the sum of its 16 squared components.

Syntax¶

WasmGPU.math.mat4.normsq(matr: number[]): number
const result = wgpu.math.mat4.normsq(matr);

Precision-Specific Wasm Forms¶

WasmGPU.math.mat4f.normsq(m: WasmPtr): number
WasmGPU.math.mat4d.normsq(m: WasmPtr): number

These forms use caller-owned pointers to 16-element matrix blocks in WasmGPU driver memory: binary32 for mat4f and binary64 for mat4d. Methods with an output pointer write that block instead of allocating a JavaScript array. See WasmGPU.math for allocation, views, aliasing, and release requirements.

Parameters¶

Name	Type	Required	Description
`matr`	`number[]`	Yes	Column-major 4x4 matrix whose squared Frobenius norm is returned.

Returns¶

number - Squared Euclidean norm of the input.

Type Details¶

type Mat4 = number[]; // expected length: 16 (4x4, column-major)

Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const matr = wgpu.math.mat4.translate(wgpu.math.mat4.identity(), [1, 2, 3]);
const result = wgpu.math.mat4.normsq(matr);
console.log(result);
