Crate scirs2_wasm 

SciRS2-WASM: WebAssembly Bindings for SciRS2

High-performance scientific computing in the browser and Node.js.

Features

• Pure Rust: 100% safe Rust code compiled to WASM
• SIMD Support: Optional WASM SIMD (wasm32-simd128) acceleration
• Async Operations: Non-blocking computations with async/await
• TypeScript Support: Full TypeScript type definitions
• Memory Efficient: Optimized memory management for browser environments
• Zero-copy: Direct array buffer access when possible

Modules

• array: N-dimensional array operations
• linalg: Linear algebra (matrix operations, decompositions)
• stats: Statistical functions (distributions, tests, descriptive stats)
• fft: Fast Fourier Transform operations
• signal: Signal processing (filtering, convolution, wavelets)
• integrate: Numerical integration and ODE solvers
• interpolate: Interpolation (linear, spline, Lagrange, PCHIP, Akima)
• optimize: Optimization algorithms (minimize, curve fitting)
• random: Random number generation and distributions

Example Usage (JavaScript)

import * as scirs2 from 'scirs2-wasm';

// Initialize the library
await scirs2.default();

// Create arrays
const a = scirs2.array([1, 2, 3, 4]);
const b = scirs2.array([5, 6, 7, 8]);

// Perform operations
const sum = scirs2.add(a, b);
const dot = scirs2.dot(a, b);

// Statistical operations
const mean = scirs2.mean(a);
const std = scirs2.std(a);

// Linear algebra
const matrix = scirs2.array2d([[1, 2], [3, 4]]);
const inv = scirs2.inv(matrix);
const det = scirs2.det(matrix);
