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.
