    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>

npm install @stdlib/blas-base-matrix-orientations
```

</section>

<section class="usage">

## Usage

```javascript
var orientations = require( '@stdlib/blas-base-matrix-orientations' );
```

#### orientations()

Returns a list of matrix orientations.

```javascript
var out = orientations();
// e.g., returns [ 'rows', 'columns' ]
```

The output array contains the following types:

-   `rows`: data is stored along matrix rows.
-   `columns`: data is stored along matrix columns.

<!-- eslint no-undef: "error" -->

```javascript
var contains = require( '@stdlib/array-base-assert-contains' ).factory;
var orientations = require( '@stdlib/blas-base-matrix-orientations' );

var isMatrixOrientation = contains( orientations() );

var bool = isMatrixOrientation( 'rows' );
// returns true

bool = isMatrixOrientation( 'columns' );
// returns true

bool = isMatrixOrientation( 'beep' );

### Usage

```c
#include "stdlib/blas/base/matrix_orientations.h"
```

#### STDLIB_BLAS_MATRIX_ORIENTATION

An enumeration of matrix orientations with the following fields:

-   **STDLIB_BLAS_ROW_MATRIX**: data is stored along matrix rows.
-   **STDLIB_BLAS_COLUMN_MATRIX**: data is stored along matrix columns.

```c
#include "stdlib/blas/base/matrix_orientations.h"

const enum STDLIB_BLAS_MATRIX_ORIENTATION v = STDLIB_BLAS_ROW_MATRIX;
```

### Notes

-   Enumeration constants should be considered opaque values, and one should **not** rely on specific integer values.
