Generate a logarithmically spaced numeric array.
npm install @stdlib/array-logspace
Alternatively,
- To load the package in a website via a
script
tag without installation and bundlers, use the ES Module available on theesm
branch. - If you are using Deno, visit the
deno
branch. - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umd
branch.
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
var logspace = require( '@stdlib/array-logspace' );
Generates a logarithmically spaced numeric array
between 10^a
and 10^b
. If a length
is not provided, the default output array
length is 10
.
var arr = logspace( 0, 2, 6 );
// returns [ 1, ~2.5, ~6.31, ~15.85, ~39.81, 100 ]
- The output
array
includes the values10^a
and10^b
. Beware of floating point errors, including for the first and lastarray
elements.
var logspace = require( '@stdlib/array-logspace' );
var out;
// Default behavior:
out = logspace( 0, 3 );
console.log( out.join( '\n' ) );
// Specify length:
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' ) );
