Unary

[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]

Apply a unary callback to elements in a strided input array and assign results to elements in a strided output array.

Installation

npm install @stdlib/strided-base-unary

Usage

var unary = require( '@stdlib/strided-base-unary' );

unary( arrays, shape, strides, fcn )

Applies a unary callback to elements in a strided input array and assigns results to elements in a strided output array.

var Float64Array = require( '@stdlib/array-float64' );
var abs = require( '@stdlib/math-base-special-abs' );

var x = new Float64Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );

// Compute the absolute values in-place:
unary( [ x, x ], [ x.length ], [ 1, 1 ], abs );
// x => <Float64Array>[ 2.0, 1.0, 3.0, 5.0, 4.0, 0.0, 1.0, 3.0 ]

The function accepts the following arguments:

• arrays: array-like object containing one strided input array and one strided output array.
• shape: array-like object containing a single element, the number of indexed elements.
• strides: array-like object containing the stride lengths for the strided input and output arrays.
• fcn: unary function to apply.

The shape and strides parameters determine which elements in the strided input and output arrays are accessed at runtime. For example, to index every other value in the strided input array and to index the first N elements of the strided output array in reverse order,

var Float64Array = require( '@stdlib/array-float64' );
var abs = require( '@stdlib/math-base-special-abs' );

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0, -6.0 ] );
var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

var N = 3;

unary( [ x, y ], [ N ], [ 2, -1 ], abs );
// y => <Float64Array>[ 5.0, 3.0, 1.0, 0.0, 0.0, 0.0 ]

Note that indexing is relative to the first index. To introduce an offset, use [typed array][mdn-typed-array] views.

var Float64Array = require( '@stdlib/array-float64' );
var abs = require( '@stdlib/math-base-special-abs' );

// Initial arrays...
var x0 = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0, -6.0 ] );
var y0 = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

// Create offset views...
var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*3 ); // start at 4th element

var N = 3;

unary( [ x1, y1 ], [ N ], [ -2, 1 ], abs );
// y0 => <Float64Array>[ 0.0, 0.0, 0.0, 6.0, 4.0, 2.0 ]

unary.ndarray( arrays, shape, strides, offsets, fcn )

Applies a unary callback to elements in a strided input array and assigns results to elements in a strided output array using alternative indexing semantics.

var Float64Array = require( '@stdlib/array-float64' );
var abs = require( '@stdlib/math-base-special-abs' );

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0 ] );
var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] );

unary.ndarray( [ x, y ], [ x.length ], [ 1, 1 ], [ 0, 0 ], abs );
// y => <Float64Array>[ 1.0, 2.0, 3.0, 4.0, 5.0 ]

The function accepts the following additional arguments:

• offsets: array-like object containing the starting indices (i.e., index offsets) for the strided input and output arrays.

While [typed array][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offsets parameter supports indexing semantics based on starting indices. For example, to index every other value in the strided input array starting from the second value and to index the last N elements in the strided output array,

var Float64Array = require( '@stdlib/array-float64' );
var abs = require( '@stdlib/math-base-special-abs' );

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0, -6.0 ] );
var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

var N = 3;

unary.ndarray( [ x, y ], [ N ], [ 2, -1 ], [ 1, y.length-1 ], abs );
// y => <Float64Array>[ 0.0, 0.0, 0.0, 6.0, 4.0, 2.0 ]

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var filledarray = require( '@stdlib/array-filled' );
var filledarrayBy = require( '@stdlib/array-filled-by' );
var unary = require( '@stdlib/strided-base-unary' );

function add10( x ) {
    return x + 10;
}

var N = 10;

var x = filledarrayBy( N, 'generic', discreteUniform( -100, 100 ) );
console.log( x );

var y = filledarray( 0.0, N, 'generic' );
console.log( y );

var shape = [ N ];
var strides = [ 1, -1 ];
var offsets = [ 0, N-1 ];

unary.ndarray( [ x, y ], shape, strides, offsets, add10 );
console.log( y );

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:

stdlib_strided_<input_data_type>_<output_data_type>[_as_<callback_arg_data_type>_<callback_return_data_type>]

For example,

void stdlib_strided_d_d(...) {...}

is a function which accepts one double-precision floating-point strided input array and one double-precision floating-point strided output array. 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 strided input and/or output array data types, the naming convention supports appending an as suffix. For example,

void stdlib_strided_f_f_as_d_d(...) {...}

is a function which accepts one single-precision floating-point strided input array and one single-precision floating-point strided output array. 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

// 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 strided input array and the callback (i.e., the input argument and return value) share the same data type, the as suffix can be omitted. For example,

void stdlib_strided_f_d(...) {...}

is a function which accepts one single-precision floating-point strided input array and one double-precision floating-point strided output array. 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

// 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;
