About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, wellwritten, studied, documented, tested, measured, and highquality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
gdot
Calculate the dot product of two vectors.
The dot product (or scalar product) is defined as
Installation
npm install @stdlib/blasgdot
Usage
var gdot = require( '@stdlib/blasgdot' );
gdot( x, y )
Calculates the dot product of vectors x
and y
.
var Int32Array = require( '@stdlib/arrayint32' );
var array = require( '@stdlib/ndarrayarray' );
var x = array( new Int32Array( [ 4.0, 2.0, 3.0, 5.0, 1.0 ] ) );
var y = array( new Int32Array( [ 2.0, 6.0, 1.0, 4.0, 8.0 ] ) );
var z = gdot( x, y );
// returns 5.0
The function has the following parameters:

x: a 1dimensional
ndarray
or an arraylike object. 
y: a 1dimensional
ndarray
or an arraylike object.
If provided empty vectors, the function returns 0.0
.
var z = gdot( [], [] );
// returns 0.0
Notes
Examples
var discreteUniform = require( '@stdlib/randombasediscreteuniform' );
var gdot = require( '@stdlib/blasgdot' );
var rand1 = discreteUniform.factory( 0, 100 );
var rand2 = discreteUniform.factory( 0, 10 );
var x = [];
var y = [];
var i;
for ( i = 0; i < 10; i++ ) {
x.push( rand1() );
y.push( rand2() );
}
console.log( x );
console.log( y );
var z = gdot( x, y );
console.log( z );
