Logspace
Generate a logarithmically spaced numeric array.
Usage
var logspace = require( '@stdlib/array/logspace' );
logspace( a, b[, length] )
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 ]
Notes
- The output
array
includes the values10^a
and10^b
. Beware of floating point errors, including for the first and lastarray
elements.
Examples
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' ) );
