    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

```bash
npm install @stdlib/complex-base-wrap-function
```

</section>

<section class="usage">

## Usage

```javascript
var wrap = require( '@stdlib/complex-base-wrap-function' );
```

#### wrap( fcn, nargs, ctor )

Returns a function which wraps a function accepting complex number arguments to support providing both real and complex numbers.

```javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );
var caddf = require( '@stdlib/complex-float32-base-add' );

var f = wrap( caddf, 2, Complex64 );
// returns <Function>
```

The function accepts the following arguments:

-   **fcn**: the function to wrap.
-   **nargs**: the number of arguments to be provided to the wrapped function.
-   **ctor**: complex number constructor for converting real numbers to complex numbers.

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   The returned function **assumes** that the wrapped function accepts **only** complex number input arguments (i.e., every argument must be a complex number).
-   The returned function **assumes** that, if an input argument is non-numeric (i.e., not of type `number`), then the input argument is a complex number. The returned function does **not** verify that non-numeric input arguments are, in fact, complex number objects. The returned function passes non-numeric input arguments to the wrapped function without modification.

## Examples

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

```javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );
var caddf = require( '@stdlib/complex-float32-base-add' );
var wrap = require( '@stdlib/complex-base-wrap-function' );

var f = wrap( caddf, 2, Complex64 );

// ...

var z = f( 3.0, 4.0 );
// returns <Complex64>[ 7.0, 0.0 ]

console.log( z.toString() );
// => '7 + 0i'
