    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>

## Usage

```javascript
var complementShape = require( '@stdlib/ndarray-base-complement-shape' );
```

#### complementShape( shape, dims )

Returns the shape defined by the dimensions which are not included in a list of dimensions.

```javascript
var sh = complementShape( [ 3, 2 ], [ -1 ] );
// returns [ 3 ]
```

The function accepts the following parameters:

-   **shape**: array shape.
-   **dims**: list of dimensions.
