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!

Assigns callbacks to binary interfaces according to type promotion rules.

The function accepts the following arguments:
 table: callback table.
 signatures: strided array containing binary interface signatures.
A callback table
should have the following properties:
 default: default callback.
 complex64: callback for singleprecision complex floatingpoint numbers.
 complex128: callback for doubleprecision complex floatingpoint numbers.

The function assumes that the provided signature array has the following properties:
 a strided array having a stride length of
3
(i.e., every3
elements define a binary interface signature).  for each signature (i.e., set of three consecutive nonoverlapping strided array elements), the first two elements are the input data types and the third element is the return data type.
 all signatures follow type promotion rules.
 a strided array having a stride length of
var dtypes = require( '@stdlib/strideddtypes' );

var add = require( '@stdlib/mathbaseopsadd' );
var cadd = require( '@stdlib/complexfloat64baseadd' );
var caddf = require( '@stdlib/complexfloat32baseadd' );
var callbacks = require( '@stdlib/stridedbasebinarysignaturecallbacks' );
// Get the list of supported strided array data types:
var dt = dtypes();
// Generate binary interface signatures:

// Define a callback table:
var table = {

};

@stdlib/stridedbase/binarydtypesignatures
: generate a list of binary interface signatures from strided array data types.
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
