## 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 <Int32Array>[ 1, 2, 3, 4, 5 ] | ||
``` | ||

||
## Notes | ||
|
||
- For complex number arrays, each element of the returned array has an imaginary component equal to `0`. | ||

```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 ); | ||
