> Computes the L1 norm (Manhattan/Taxicab norm)) of an array of values.
`` bash`
$ npm install compute-l1norm
For use in the browser, use browserify.
To use the module,
` javascript`
var l1norm = require( 'compute-l1norm' );
#### l1norm( arr )
Computes the _L1_ norm (Manhattan/Taxicab norm) of an array of values.
` javascript
var data = [ 2, 7, 3, -3, 9 ];
var norm = l1norm( data );
// returns 24
`
` javascript
var l1norm = require( 'compute-l1norm' );
var data = new Array( 1000 );
for ( var i = 0; i < data.length; i++ ) {
data[ i ] = Math.random()*100 - 50;
}
console.log( l1norm( data ) );
`
To run the example code from the top-level application directory,
` bash`
$ node ./examples/index.js
Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:
` bash`
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:
` bash`
$ make test-cov
Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,
` bash``
$ make view-cov
