Package Exports

@stdlib/array-base-logspace
@stdlib/array-base-logspace/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/array-base-logspace) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

logspace

Generate a logarithmically spaced numeric array.

Installation

npm install @stdlib/array-base-logspace

Usage

var logspace = require( '@stdlib/array-base-logspace' );

logspace( a, b, length )

Generates a logarithmically spaced numeric array between 10^a and 10^b.

var arr = logspace( 0, 2, 6 );
// returns [ 1, ~2.5, ~6.31, ~15.85, ~39.81, 100 ]

Notes

The output array includes the values 10^a and 10^b. Beware of floating point errors, including for the first and last array elements.

Examples

var logspace = require( '@stdlib/array-base-logspace' );

var out = logspace( 0, 3, 100 );
console.log( out.join( '\n' ) );

// Create an array with decremented values:
out = logspace( 3, 0, 10 );
console.log( out.join( '\n' ) );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
