Symmetric banded array utilities.
npm install @stdlib/array-base-symmetric-bandedWe 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. 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. 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. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Symmetric banded array utilities.
``bash`
npm install @stdlib/array-base-symmetric-banded
`javascript`
var ns = require( '@stdlib/array-base-symmetric-banded' );
#### ns
Namespace containing symmetric banded array utilities.
`javascript`
var o = ns;
// returns {...}
The namespace exports the following:
- [filled2dBy( N, k, fill, clbk[, thisArg] )][@stdlib/array/base/symmetric-banded/filled2d-by]: create a filled two-dimensional symmetric banded nested array according to a provided callback function.
- [toCompact( uplo, arr, k, colexicographic )][@stdlib/array/base/symmetric-banded/to-compact]: convert a two-dimensional symmetric banded nested array to compact banded storage.
`javascript
var objectKeys = require( '@stdlib/utils-keys' );
var ns = require( '@stdlib/array-base-symmetric-banded' );
console.log( objectKeys( ns ) );

This package is part of [stdlib][stdlib], a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
