exact-linspace

MATLAB-inspired function to create linearly spaced values.

Importing this function

Node Modules

• Run npm install exact-linspace
• Add an import to the npm package import linspace from 'exact-linspace';
• Then you can use the function in your code.

CDN

• Put the following script tag <script src='https://cdn.jsdelivr.net/npm/exact-linspace@1/dist/exact-linspace.umd.min.js'></script> in the head of your index.html
• Then you can use the function in your code.

API

ys = linspace(x1, x2);
ys = linspace(x1, x2, n);

The function takes the following arguments:

• x1: First endpoint.
• x2: Second endpoint.
• n: Total number of values. Defaults to 100.

It returns an array of n values between x1 and x2 including the endpoints.

Examples

It returns n evenly spaced values:

var ys = linspace(-5, 5, 7);
console.log(ys);
// expected output: Array [-5.0000, -3.3333, -1.6667, 0, 1.6667, 3.3333, 5.0000]

It returns a descending array if x2 is less than x1:

var ys = linspace(3, -2, 6);
console.log(ys);
// expected output: Array [3, 2, 1, 0, -1, -2]

It returns 100 values by default:

var ys = linspace(1, 100);
console.log(ys);
// expected output: Array [1, 2, 3, ..., 98, 99, 100]

It returns x2 if n is equal to one:

var ys = linspace(-7, 2, 1);
console.log(ys);
// expected output: Array [2]

It returns an empty array if n is less than or equal to zero:

var ys = linspace(2, 4, -1);
console.log(ys);
// expected output: Array []

It rounds down n if n is not an integer:

var ys = linspace(4, 6, 3.14);
console.log(ys);
// expected output: Array [4, 5, 6]
