Compares performance of the single precision BLAS saxpy routine between WebAssembly (using AssemblyScript), TypeScript, C (Node.js addon) and nblas. Here is the reference implementation for the saxpy routine.

Files:

• src/saxpy.ts – TypeScript implementation
• c/saxpy.cc – C implementation
• assembly/saxpy.ts – AssemblyScript implementation
• assembly/index.ts – Entry point for AssemblyScript compilation

npm install
npm run build
