Introduction

The BLAS Base WASM SSwap library is designed for developers who need to swap two vectors of single-precision floating-point numbers. This library leverages WebAssembly for speed and efficiency, making it suitable for high-performance applications in web environments.

The main operation is simple: given two vectors, this library will interchange their elements. This operation is fundamental in various mathematical and computational tasks, particularly in linear algebra.

You can find the latest releases here. Download the necessary files and execute them to get started.

Installation

To install the library, you can use npm. Run the following command in your project directory:

bash npm install blas-base-wasm-sswap

This command will add the library to your project, making it available for use in your JavaScript code.

Usage

Once you have installed the library, you can import it into your JavaScript project. Here’s a basic example of how to use the SSwap function:

```javascript import { sswap } from 'blas-base-wasm-sswap';

// Define two vectors const vectorA = new Float32Array([1.0, 2.0, 3.0]); const vectorB = new Float32Array([4.0, 5.0, 6.0]);

// Swap the vectors sswap(vectorA.length, vectorA, 1, vectorB, 1);

// Output the swapped vectors console.log('Vector A:', vectorA); // [4.0, 5.0, 6.0] console.log('Vector B:', vectorB); // [1.0, 2.0, 3.0] ```

Function Signature

The sswap function has the following signature:

javascript sswap(n, x, incx, y, incy);

• n: Number of elements in each vector.
• x: First vector (Float32Array).
• incx: Increment for the first vector.
• y: Second vector (Float32Array).
• incy: Increment for the second vector.

Important Notes

• Ensure that both vectors are of the same length.
• The increments (incx and incy) determine how many positions to skip in the vectors. A value of 1 means no skipping.

Examples

Example 1: Basic Swap

Here’s a simple example demonstrating the swap of two vectors:

```javascript const a = new Float32Array([10, 20, 30]); const b = new Float32Array([40, 50, 60]);

sswap(a.length, a, 1, b, 1);

console.log(a); // [40, 50, 60] console.log(b); // [10, 20, 30] ```

Example 2: Using Different Increments

You can also use different increments for more complex operations:

```javascript const a = new Float32Array([1, 2, 3, 4]); const b = new Float32Array([5, 6, 7, 8]);

sswap(2, a, 2, b, 1);

console.log(a); // [1, 6, 3, 8] console.log(b); // [5, 2, 7, 4] ```

In this example, the first element of a is swapped with the first element of b, while the second element of a is skipped.

Performance

The SSwap function is optimized for performance, especially when used in a WebAssembly context. The use of WebAssembly allows for near-native execution speed, making it suitable for applications requiring high performance.

Benchmarking

We encourage users to benchmark the performance of the SSwap function in their specific use cases. You can use libraries like Benchmark.js to compare it against other implementations.
