This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/ndarray-base-ndarraylike2scalar) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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, well-written, studied, documented, tested, measured, and high-quality 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!

ndarraylike2scalar

Convert an ndarray-like object to a scalar value.

Installation

npm install @stdlib/ndarray-base-ndarraylike2scalar

Usage

var ndarraylike2scalar = require( '@stdlib/ndarray-base-ndarraylike2scalar' );

ndarraylike2scalar( x )

Converts an ndarray-like object to a scalar value.

var scalar2ndarray = require( '@stdlib/ndarray-from-scalar' );

var arr = scalar2ndarray( 1.0 );
// returns <ndarray>

var out = ndarraylike2scalar( arr );
// returns 1.0

Examples

var scalar2ndarray = require( '@stdlib/ndarray-from-scalar' );
var compose = require( '@stdlib/utils-compose' );
var naryFunction = require( '@stdlib/utils-nary-function' );
var oneTo = require( '@stdlib/array-one-to' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var ndarraylike2scalar = require( '@stdlib/ndarray-base-ndarraylike2scalar' );

// Create a list of scalars:
var scalars = oneTo( 10 );

// Create a composite function which round-trips a scalar to an ndarray and back:
var f = compose( ndarraylike2scalar, naryFunction( scalar2ndarray, 1 ) );

// Apply the function to the list of scalars:
logEachMap( '%d => %d', scalars, f );

Notice

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.
