Examples

var blas = require( 'blas' );
 
var rand;
var sign;
var x;
var y;
var i;
 
= new Float64Array( 100 );
for ( i = 0; i < x.length; i++ ) {
    rand = Math.round( Math.random()*100.0 );
    sign = Math.random();
    if ( sign < 0.5 ) {
        sign = -1.0;
    } else {
        sign = 1.0;
    }
    x[ i ] = sign * rand;
}
console.log( blas.dasum( x.length, x, 1 ) );
 
= new Float64Array( 10 );
= new Float64Array( 10 );
for ( i = 0; i < x.length; i++ ) {
    x[ i ] = Math.round( Math.random()*500.0 );
    y[ i ] = Math.round( Math.random()*255.0 );
}
console.log( x );
console.log( y );
 
// Copy elements from `x` into `y` starting from the end of `y`:
blas.dcopy( x.length, x, 1, y, -1 );
console.log( y );

To run the example code from the top-level application directory,

$ node ./examples/index.js

Tests

Unit

This repository uses tape for unit tests. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

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:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov
