    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="installation">

## Installation

```bash
npm install @stdlib/ndarray-vector-uint8c
```

</section>

<section class="usage">

## Usage

```javascript
var Uint8ClampedVector = require( '@stdlib/ndarray-vector-uint8c' );
```

#### Uint8ClampedVector( \[options] )

Returns a one-dimensional clamped unsigned 8-bit integer [ndarray][@stdlib/ndarray/ctor].

```javascript
var numel = require( '@stdlib/ndarray-numel' );

var arr = new Uint8ClampedVector();
// returns <ndarray>

var len = numel( arr );
// returns 0
```

The function accepts the following options:

-   **order**: specifies whether an [ndarray][@stdlib/ndarray/ctor] is `'row-major'` (C-style) or `'column-major'` (Fortran-style). Default: `'row-major'`.
-   **mode**: specifies how to handle indices which exceed array dimensions (see [`ndarray`][@stdlib/ndarray/ctor]). Default: `'throw'`.
-   **readonly**: boolean indicating whether an array should be **read-only**. Default: `false`.

#### Uint8ClampedVector( length\[, options] )

Returns a one-dimensional clamped unsigned 8-bit integer [ndarray][@stdlib/ndarray/ctor] having a specified `length`.

```javascript
var numel = require( '@stdlib/ndarray-numel' );

var arr = new Uint8ClampedVector( 5 );
// returns <ndarray>

var len1 = numel( arr );
// returns 5
```

#### Uint8ClampedVector( obj\[, options] )

Creates a one-dimensional clamped unsigned 8-bit integer [ndarray][@stdlib/ndarray/ctor] from an array-like object or iterable.

```javascript
var numel = require( '@stdlib/ndarray-numel' );

var arr = new Uint8ClampedVector( [ 1, 2, 3 ] );
// returns <ndarray>

var len1 = numel( arr );
// returns 3
```

#### Uint8ClampedVector( buffer\[, byteOffset\[, length]]\[, options] )

Returns a one-dimensional clamped unsigned 8-bit integer [ndarray][@stdlib/ndarray/ctor] view of an [`ArrayBuffer`][@stdlib/array/buffer].

```javascript
var ArrayBuffer = require( '@stdlib/array-buffer' );
var numel = require( '@stdlib/ndarray-numel' );

var buf = new ArrayBuffer( 32 );

var arr1 = new Uint8ClampedVector( buf );
// returns <ndarray>

var len1 = numel( arr1 );
// returns 32

var arr2 = new Uint8ClampedVector( buf, 16 );
// returns <ndarray>

var len2 = numel( arr2 );
// returns 16

var arr3 = new Uint8ClampedVector( buf, 16, 1 );
// returns <ndarray>

var len3 = numel( arr3 );
// returns 1
```

## Examples

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

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var sum = require( '@stdlib/blas-ext-sum' );
var map = require( '@stdlib/ndarray-map' );
var Uint8ClampedVector = require( '@stdlib/ndarray-vector-uint8c' );

// Create a vector containing random values:
var x = new Uint8ClampedVector( discreteUniform( 10, 0, 100 ) );

// Compute the sum:
var v = sum( x );
console.log( v.get() );

// Define a function which applies a threshold to individual values:
function threshold( v ) {
    return ( v > 10 ) ? v : 0;
}

// Apply threshold:
var y = map( x, threshold );

// Recompute the sum:
v = sum( y );
console.log( v.get() );
```
