    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>

<section class="usage">

## Usage

```javascript
var resolve = require( '@stdlib/ndarray-base-output-policy-resolve-str' );
```

#### resolve( dtype )

Returns the policy string associated with an ndarray [data type policy][@stdlib/ndarray/output-dtype-policies] value.

```javascript
var str2enum = require( '@stdlib/ndarray-base-output-policy-str2enum' );

var v = resolve( 'same' );
// returns 'same'

v = resolve( str2enum( 'same' ) );
// returns 'same'
```

If unable to resolve a policy string, the function returns `null`.

```javascript
var v = resolve( 'beep' );
// returns null
```
