About stdlib...
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.
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.
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.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
# oneToLike

> Generate a linearly spaced numeric array whose elements increment by `1` starting from one and having the same length and data type as a provided input array.
## Installation
```bash
npm install @stdlib/array-one-to-like
```
Alternatively,
- To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]).
- If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions).
- For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]).
The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
## Usage
```javascript
var oneToLike = require( '@stdlib/array-one-to-like' );
```
#### oneToLike( x\[, dtype] )
Generates a linearly spaced numeric array whose elements increment by `1` starting from one and having the same length and data type as a provided input array `x`.
```javascript
var arr = oneToLike( [ 0, 0, 0, 0, 0 ] );
// returns [ 1, 2, 3, 4, 5 ]
```
The function recognizes the following data types:
- `float64`: double-precision floating-point numbers (IEEE 754)
- `float32`: single-precision floating-point numbers (IEEE 754)
- `complex128`: double-precision complex floating-point numbers
- `complex64`: single-precision complex floating-point numbers
- `int32`: 32-bit two's complement signed integers
- `uint32`: 32-bit unsigned integers
- `int16`: 16-bit two's complement signed integers
- `uint16`: 16-bit unsigned integers
- `int8`: 8-bit two's complement signed integers
- `uint8`: 8-bit unsigned integers
- `uint8c`: 8-bit unsigned integers clamped to `0-255`
- `generic`: generic JavaScript values
By default, the output array data type is inferred from the provided array `x`. To return an array having a different data type, provide a `dtype` argument.
```javascript
var arr = oneToLike( [ 0, 0, 0, 0, 0 ], 'int32' );
// returns [ 1, 2, 3, 4, 5 ]
```
## Notes
- For complex number arrays, each element of the returned array has an imaginary component equal to `0`.
## Examples
```javascript
var sort2hp = require( '@stdlib/blas-ext-base-gsort2hp' );
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var oneToLike = require( '@stdlib/array-one-to-like' );
// Generate an array of random numbers:
var opts = {
'dtype': 'generic'
};
var x = discreteUniform( 10, 100, 200, opts );
// Generate a linearly-spaced array:
var y = oneToLike( x );
// Create a temporary array to avoid mutation:
var tmp = x.slice();
// Sort `y` according to the sort order of `x`:
sort2hp( x.length, 1, tmp, 1, y, 1 );
console.log( x );
console.log( y );
```
