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, wellwritten, studied, documented, tested, measured, and highquality 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
npm install @stdlib/arrayonetolike
Usage
var oneToLike = require( '@stdlib/arrayonetolike' );
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
.
var arr = oneToLike( [ 0, 0, 0, 0, 0 ] );
// returns [ 1, 2, 3, 4, 5 ]
The function recognizes the following data types:

float64
: doubleprecision floatingpoint numbers (IEEE 754) 
float32
: singleprecision floatingpoint numbers (IEEE 754) 
complex128
: doubleprecision complex floatingpoint numbers 
complex64
: singleprecision complex floatingpoint numbers 
int32
: 32bit two's complement signed integers 
uint32
: 32bit unsigned integers 
int16
: 16bit two's complement signed integers 
uint16
: 16bit unsigned integers 
int8
: 8bit two's complement signed integers 
uint8
: 8bit unsigned integers 
uint8c
: 8bit unsigned integers clamped to0255

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.
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
.
Examples
var sort2hp = require( '@stdlib/blasextbasegsort2hp' );
var discreteUniform = require( '@stdlib/randomarraydiscreteuniform' );
var oneToLike = require( '@stdlib/arrayonetolike' );
// Generate an array of random numbers:
var opts = {
'dtype': 'generic'
};
var x = discreteUniform( 10, 100, 200, opts );
// Generate a linearlyspaced 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 );
