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!

Nullary

Apply a nullary callback and assign results to elements in an output ndarray.

## Installation ```bash npm install @stdlib/ndarray-base-nullary ``` Alternatively, - To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]). - If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions). - For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]). The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships. To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

## Usage ```javascript var nullary = require( '@stdlib/ndarray-base-nullary' ); ``` #### nullary( arrays, fcn ) Applies a nullary callback and assigns results to elements in an output ndarray. ```javascript var Float64Array = require( '@stdlib/array-float64' ); function fcn() { return 10.0; } // Create data buffers: var xbuf = new Float64Array( 12 ); // Define the shape of the output array: var shape = [ 3, 1, 2 ]; // Define the array strides: var sx = [ 4, 4, 1 ]; // Define the index offset: var ox = 1; // Create the output ndarray-like object: var x = { 'dtype': 'float64', 'data': xbuf, 'shape': shape, 'strides': sx, 'offset': ox, 'order': 'row-major' }; // Apply the nullary function: nullary( [ x ], fcn ); console.log( x.data ); // => [ 0.0, 10.0, 10.0, 0.0, 0.0, 10.0, 10.0, 0.0, 0.0, 10.0, 10.0, 0.0 ] ``` The function accepts the following arguments: - **arrays**: array-like object containing an output ndarray. - **fcn**: nullary function to apply. The provided ndarray should be an `object` with the following properties: - **dtype**: data type. - **data**: data buffer. - **shape**: dimensions. - **strides**: stride lengths. - **offset**: index offset. - **order**: specifies whether an ndarray is row-major (C-style) or column major (Fortran-style).

## Notes - For very high-dimensional ndarrays which are non-contiguous, one should consider copying the underlying data to contiguous memory before applying a nullary function in order to achieve better performance.

## Examples ```javascript var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory; var filledarray = require( '@stdlib/array-filled' ); var ndarray2array = require( '@stdlib/ndarray-base-to-array' ); var nullary = require( '@stdlib/ndarray-base-nullary' ); var x = { 'dtype': 'generic', 'data': filledarray( 0, 10, 'generic' ), 'shape': [ 5, 2 ], 'strides': [ 2, 1 ], 'offset': 0, 'order': 'row-major' }; nullary( [ x ], discreteUniform( -100, 100 ) ); console.log( ndarray2array( x.data, x.shape, x.strides, x.offset, x.order ) ); ```

## C APIs

Character codes for data types: - **x**: `bool` (boolean). - **z**: `complex128` (double-precision floating-point complex number). - **c**: `complex64` (single-precision floating-point complex number). - **f**: `float32` (single-precision floating-point number). - **d**: `float64` (double-precision floating-point number). - **k**: `int16` (signed 16-bit integer). - **i**: `int32` (signed 32-bit integer). - **s**: `int8` (signed 8-bit integer). - **t**: `uint16` (unsigned 16-bit integer). - **u**: `uint32` (unsigned 32-bit integer). - **b**: `uint8` (unsigned 8-bit integer). Function name suffix naming convention: ```text stdlib_ndarray_[_as_] ``` For example, ```c void stdlib_ndarray_d(...) {...} ``` is a function which accepts one double-precision floating-point output ndarray. In other words, the suffix encodes the function type signature. To support callbacks whose return values are of a different data type than the output ndarray data types, the naming convention supports appending an `as` suffix. For example, ```c void stdlib_ndarray_f_as_d(...) {...} ``` is a function which accepts one single-precision floating-point output ndarray. However, the callback returns double-precision floating-point numbers. Accordingly, the output values need to be cast using the following conversion sequence ```c // Evaluate the callback: double out = f(); // Convert the callback return value to single-precision: x[ i ] = (float)out; ```
