    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>

## Installation

```

<section class="usage">

## Usage

```javascript
var pickArguments = require( '@stdlib/utils-pick-arguments' );
```

#### pickArguments( fcn, indices\[, thisArg] )

Returns a `function` that invokes a provided function with specified arguments.

```javascript
function foo( a, b ) {
    return [ a, b ];
}

var bar = pickArguments( foo, [ 0, 2 ] );

var out = bar( 1, 2, 3 );
// returns [ 1, 3 ]
```

To set the `this` context when invoking the provided function, provide a `thisArg`.

<!-- eslint-disable no-restricted-syntax -->

```javascript
function Foo() {
    this.x = 1;
    this.y = 2;
}

Foo.prototype.scale = function scale( a, b ) {
    return [ this.x*a, this.y*b ];
};

var ctx = {
    'x': 10,
    'y': 20
};

var foo = new Foo();

var bar = pickArguments( foo.scale, [ 0, 2 ], ctx );

var out = bar( 1, 2, 3 );
// returns [ 10, 60 ]
```

    f = pickArguments( add, [ i-1, i ] );
    console.log( 'sum(x_%d, x_%d) = %d', i-1, i, f.apply( null, x ) );
