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!

Unary

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

## Installation ```bash npm install @stdlib/ndarray-base-unary ``` 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 unary = require( '@stdlib/ndarray-base-unary' ); ``` #### unary( arrays, fcn ) Applies a unary callback to elements in an input ndarray and assigns results to elements in an output ndarray. ```javascript var Float64Array = require( '@stdlib/array-float64' ); function scale( x ) { return x * 10.0; } // Create data buffers: var xbuf = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] ); var ybuf = new Float64Array( 6 ); // Define the shape of the input and output arrays: var shape = [ 3, 1, 2 ]; // Define the array strides: var sx = [ 4, 4, 1 ]; var sy = [ 2, 2, 1 ]; // Define the index offsets: var ox = 1; var oy = 0; // Create the input and output ndarray-like objects: var x = { 'dtype': 'float64', 'data': xbuf, 'shape': shape, 'strides': sx, 'offset': ox, 'order': 'row-major' }; var y = { 'dtype': 'float64', 'data': ybuf, 'shape': shape, 'strides': sy, 'offset': oy, 'order': 'row-major' }; // Apply the unary function: unary( [ x, y ], scale ); console.log( y.data ); // => [ 20.0, 30.0, 60.0, 70.0, 100.0, 110.0 ] ``` The function accepts the following arguments: - **arrays**: array-like object containing one input ndarray and one output ndarray. - **fcn**: unary function to apply. Each 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 unary 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 filledarrayBy = require( '@stdlib/array-filled-by' ); var abs = require( '@stdlib/math-base-special-abs' ); var shape2strides = require( '@stdlib/ndarray-base-shape2strides' ); var ndarray2array = require( '@stdlib/ndarray-base-to-array' ); var unary = require( '@stdlib/ndarray-base-unary' ); var N = 10; var x = { 'dtype': 'generic', 'data': filledarrayBy( N, 'generic', discreteUniform( -100, 100 ) ), 'shape': [ 5, 2 ], 'strides': [ 2, 1 ], 'offset': 0, 'order': 'row-major' }; var y = { 'dtype': 'generic', 'data': filledarray( 0, N, 'generic' ), 'shape': x.shape.slice(), 'strides': shape2strides( x.shape, 'column-major' ), 'offset': 0, 'order': 'column-major' }; unary( [ x, y ], abs ); console.log( ndarray2array( x.data, x.shape, x.strides, x.offset, x.order ) ); console.log( ndarray2array( y.data, y.shape, y.strides, y.offset, y.order ) ); ```

## C APIs

Character codes for data types: - **x**: `bool` (boolean). - **c**: `complex64` (single-precision floating-point complex number). - **z**: `complex128` (double-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_d(...) {...} ``` is a function which accepts one double-precision floating-point input ndarray and one double-precision floating-point output ndarray. In other words, the suffix encodes the function type signature. To support callbacks whose input arguments and/or return values are of a different data type than the input and/or output ndarray data types, the naming convention supports appending an `as` suffix. For example, ```c void stdlib_ndarray_f_f_as_d_d(...) {...} ``` is a function which accepts one single-precision floating-point input ndarray and one single-precision floating-point output ndarray. However, the callback accepts and returns double-precision floating-point numbers. Accordingly, the input and output values need to be cast using the following conversion sequence ```c // Convert each input array element to double-precision: double in1 = (double)x[ i ]; // Evaluate the callback: double out = f( in1 ); // Convert the callback return value to single-precision: y[ i ] = (float)out; ``` When the input ndarray and the callback (i.e., the input argument and return value) share the same data type, the `as` suffix can be omitted. For example, ```c void stdlib_ndarray_f_d(...) {...} ``` is a function which accepts one single-precision floating-point input ndarray and one double-precision floating-point output ndarray. The callback is assumed to accept and return single-precision floating-point numbers. Accordingly, the input and output values are cast according to the following conversion sequence ```c // Retrieve each input array element as single-precision: float in1 = (float)x[ i ]; // Evaluate the callback: float out = f( in1 ); // Convert the callback return value to double-precision: y[ i ] = (double)out; ```
