    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>

> Test if a value is a 2-dimensional [ndarray][@stdlib/ndarray/ctor]-like object containing single-precision floating-point numbers.

<section class="installation">

## Installation

```bash
npm install @stdlib/assert-is-float32matrix-like
```

</section>

<section class="usage">

## Usage

```javascript
var isFloat32MatrixLike = require( '@stdlib/assert-is-float32matrix-like' );
```

#### isFloat32MatrixLike( value )

Tests if a value is a 2-dimensional [ndarray][@stdlib/ndarray/ctor]-like object whose underlying data type is `float32`.

```javascript
var Float32Array = require( '@stdlib/array-float32' );
var ndarray = require( '@stdlib/ndarray-ctor' );

var arr = ndarray( 'float32', new Float32Array( [ 0, 0, 0, 0 ] ), [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );

var bool = isFloat32MatrixLike( arr );
// returns true
```

<!-- /.usage -->

<section class="examples">

## Examples

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

```javascript
var ndarray = require( '@stdlib/ndarray-ctor' );
var Float32Array = require( '@stdlib/array-float32' );
var isFloat32MatrixLike = require( '@stdlib/assert-is-float32matrix-like' );

var buffer = new Float32Array( [ 0, 0, 0, 0 ] );
var arr = ndarray( 'float32', buffer, [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );

var out = isFloat32MatrixLike( arr );
// returns true

out = isFloat32MatrixLike( [ 1, 2, 3, 4 ] );
// returns false

out = isFloat32MatrixLike( {} );
// returns false

out = isFloat32MatrixLike( null );
// returns false
