Generates a linearly spaced numeric array.
$ npm install compute-linspaceFor use in the browser, use browserify.
To use the module,
var linspace = require( 'compute-linspace' );Generates a linearly spaced numeric array. If a length is not provided, the default output array length is 100.
var arr = linspace( 0, 100, 6 );
// returns [ 0, 20, 40, 60, 80, 100 ]The output array is guaranteed to include the start and end values. Beware, however, that values between the start and end are subject to floating point errors. Hence,
var arr = linspace( 0, 1, 3 );
// returns [ 0, ~0.5, 1 ]where arr[1] is only guaranteed to be approximately equal to 0.5. If you desire more control over element precision, consider using compute-roundn:
var roundn = require( 'compute-roundn' );
// Create an array subject to floating point errors:
var arr = linspace( 0, 1, 21 );
// Round each value to the nearest hundredth:
roundn( arr, -2 );
console.log( arr.join( '\n' ) );This function is inspired by MATLAB's linspace.
var linspace = require( 'compute-linspace' ),
out;
// Default behavior:
out = linspace( 0, 10 );
console.log( out.join( '\n' ) );
// Specify length:
out = linspace( 0, 10, 10 );
console.log( out.join( '\n' ) );
out = linspace( 0, 10, 11 );
console.log( out.join( '\n' ) );
// Create an array with decremented values:
out = linspace( 10, 0, 11 );
console.log( out.join( '\n' ) );To run the example code from the top-level application directory,
$ node ./examples/index.jsUnit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:
$ make testAll new feature development should have corresponding unit tests to validate correct functionality.
