WasmGPU.compute.CPUndarray.empty¶
Summary¶
WasmGPU.compute.CPUndarray.empty allocates a CPU-resident ndarray in WebAssembly memory.
You provide dtype and layout metadata; storage is allocated but not initialized.
Use this when you need explicit control over shape/strides before filling data.
For zero-initialized allocation, use CPUndarray.zeros.
Syntax¶
WasmGPU.compute.CPUndarray.empty(dtype: DType, layout: NdLayoutDescriptor): CPUndarray
const a = wgpu.compute.CPUndarray.empty(dtype, layout);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
dtype |
DType |
Yes | Element data type (i8, u8, i16, u16, i32, u32, f32, f64). |
layout |
NdLayoutDescriptor |
Yes | Shape plus optional byte strides and byte offset. |
Returns¶
CPUndarray - Newly allocated CPU ndarray in wasm memory.
Type Details¶
type NdLayoutDescriptor = {
shape: ReadonlyArray<number>;
stridesBytes?: ReadonlyArray<number>;
offsetBytes?: number;
};
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const a = wgpu.compute.CPUndarray.empty("f32", { shape: [4, 4] });
a.set(1.25, 0, 0);
console.log(a.get(0, 0), a.layout());
