    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

var ones = require( '@stdlib/array-base-ones' );

// Create a ones array:
var arr = ones( 10 );

// Scale element pairs...
gscal( 2, 2.0, arr, 1, 0 );
gscal( 2, 3.0, arr, 1, 2 );
gscal( 2, 4.0, arr, 1, 4 );
gscal( 2, 5.0, arr, 1, 6 );
gscal( 2, 6.0, arr, 1, 8 );

console.log( arr );
