Binary

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

Usage

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

binary( arrays, shape, strides, fcn )

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

var Float64Array = require( '@stdlib/array/float64' );

function add( x, y ) {
    return x + y;
}

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

binary( [ x, y, z ], [ x.length ], [ 1, 1, 1 ], add );
// z => <Float64Array>[ 2.0, 4.0, 6.0, 8.0, 10.0 ]

The function accepts the following arguments:

arrays: array-like object containing two strided input arrays 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: binary 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 arrays and to index the first N elements of the strided output array in reverse order,

var Float64Array = require( '@stdlib/array/float64' );

function add( x, y ) {
    return x + y;
}

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

var N = 3;

binary( [ x, y, z ], [ N ], [ 2, 2, -1 ], add );
// z => <Float64Array>[ 10.0, 6.0, 2.0, 0.0, 0.0, 0.0 ]

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

var Float64Array = require( '@stdlib/array/float64' );

function add( x, y ) {
    return x + y;
}

// Initial arrays...
var x0 = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
var y0 = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
var z0 = 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*1 ); // start at 2nd element
var z1 = new Float64Array( z0.buffer, z0.BYTES_PER_ELEMENT*3 ); // start at 4th element

var N = 3;

binary( [ x1, y1, z1 ], [ N ], [ -2, -2, 1 ], add );
// z0 => <Float64Array>[ 0.0, 0.0, 0.0, 12.0, 8.0, 4.0 ]

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

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

var Float64Array = require( '@stdlib/array/float64' );

function add( x, y ) {
    return x + y;
}

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

binary.ndarray( [ x, y, z ], [ x.length ], [ 1, 1, 1 ], [ 0, 0, 0 ], add );
// z => <Float64Array>[ 2.0, 4.0, 6.0, 8.0, 10.0 ]

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 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 arrays starting from the second value and to index the last N elements in the strided output array,

var Float64Array = require( '@stdlib/array/float64' );

function add( x, y ) {
    return x + y;
}

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

var N = 3;

binary.ndarray( [ x, y, z ], [ N ], [ 2, 2, -1 ], [ 1, 1, z.length-1 ], add );
// z => <Float64Array>[ 0.0, 0.0, 0.0, 12.0, 8.0, 4.0 ]

Examples

var discreteUniform = require( '@stdlib/random/base/discrete-uniform' ).factory;
var filledarray = require( '@stdlib/array/filled' );
var gfillBy = require( '@stdlib/blas/ext/base/gfill-by' );
var binary = require( '@stdlib/strided/base/binary' );

function add( x, y ) {
    return x + y;
}

var N = 10;

var x = filledarray( 0.0, N, 'generic' );
gfillBy( x.length, x, 1, discreteUniform( -100, 100 ) );
console.log( x );

var y = filledarray( 0.0, N, 'generic' );
gfillBy( y.length, y, 1, discreteUniform( -100, 100 ) );
console.log( y );

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

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

binary.ndarray( [ x, y, z ], shape, strides, offsets, add );
console.log( z );

C APIs

Character codes for data types:

d: float64 (double-precision floating-point number).
f: float32 (single-precision floating-point number).
s: int8 (signed 8-bit integer).
b: uint8 (unsigned 8-bit integer).
k: int16 (signed 16-bit integer).
t: uint16 (unsigned 16-bit integer).
i: int32 (signed 32-bit integer).
u: uint32 (unsigned 32-bit integer).
l: int64 (signed 64-bit integer).
v: uint64 (unsigned 64-bit integer).

Function name suffix naming convention:

stdlib_strided_<input_data_types>_<output_data_type>[_as_<callback_arg_data_types>_<callback_return_data_type>]

For example,

void stdlib_strided_dd_d(...) {...}

is a function which accepts two double-precision floating-point strided input arrays 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_ff_f_as_dd_d(...) {...}

is a function which accepts two single-precision floating-point strided input arrays 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 dx1i = (double)fx1[ i ];
double dx2i = (double)fx2[ i ];

// Evaluate the callback:
double dyi = f( dx1i, dx2i );

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