@stdlib/ndarray-base-nullary v0.2.1

Nullary

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

Installation

npm install @stdlib/ndarray-base-nullary

Usage

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

nullary( arrays, fcn )

Applies a nullary callback and assigns results to elements in an output ndarray.

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 );
// => <Float64Array>[ 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

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:

• 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:

stdlib_ndarray_<output_data_type>[_as_<callback_return_data_type>]

For example,

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,

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

// Evaluate the callback:
double out = f();

// Convert the callback return value to single-precision:
x[ i ] = (float)out;
