mskunary

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

Usage

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

mskunary( arrays, shape, strides, fcn )

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

var Float64Array = require( '@stdlib/array/float64' );
var Uint8Array = require( '@stdlib/array/uint8' );
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 ] );
var mask = new Uint8Array( [ 0, 0, 0, 1, 0, 0, 0, 1 ] );

// Compute the absolute values in-place:
mskunary( [ x, mask, x ], [ x.length ], [ 1, 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, a strided mask 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 arrays.
fcn: unary function to apply.

The shape and strides parameters determine which elements in the strided 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 Uint8Array = require( '@stdlib/array/uint8' );
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 mask = new Uint8Array( [ 0, 1, 0, 0, 0, 0 ] );
var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

mskunary( [ x, mask, y ], [ 3 ], [ 2, 1, -1 ], abs );
// y => <Float64Array>[ 5.0, 0.0, 1.0, 0.0, 0.0, 0.0 ]

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

var Float64Array = require( '@stdlib/array/float64' );
var Uint8Array = require( '@stdlib/array/uint8' );
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 m0 = new Uint8Array( [ 0, 0, 0, 0, 0, 1 ] );
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 m1 = new Uint8Array( m0.buffer, m0.BYTES_PER_ELEMENT*3 ); // start at 4th element
var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*3 ); // start at 4th element

mskunary( [ x1, m1, y1 ], [ 3 ], [ -2, 1, 1 ], abs );
// y0 => <Float64Array>[ 0.0, 0.0, 0.0, 6.0, 4.0, 0.0 ]

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

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

var Float64Array = require( '@stdlib/array/float64' );
var Uint8Array = require( '@stdlib/array/uint8' );
var abs = require( '@stdlib/math/base/special/abs' );

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0 ] );
var mask = new Uint8Array( [ 0, 0, 1, 0, 0 ] );
var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] );

mskunary.ndarray( [ x, mask, y ], [ x.length ], [ 1, 1, 1 ], [ 0, 0, 0 ], abs );
// y => <Float64Array>[ 1.0, 2.0, 0.0, 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 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 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 Uint8Array = require( '@stdlib/array/uint8' );
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 mask = new Uint8Array( [ 0, 1, 0, 0, 0, 0 ] );
var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

mskunary.ndarray( [ x, mask, y ], [ 3 ], [ 2, 1, -1 ], [ 1, 0, y.length-1 ], abs );
// y => <Float64Array>[ 0.0, 0.0, 0.0, 6.0, 0.0, 2.0 ]

Examples

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

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

var N = 10;

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

var m = filledarrayBy( N, 'generic', bernoulli( 0.5 ) );
console.log( m );

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

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

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

C APIs

Character codes for data types:

d: float64 (double-precision floating-point number).

Function name suffix naming convention:

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

For example,

void stdlib_strided_mask_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_mask_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 dxi = (double)fx[ i ];

// Evaluate the callback:
double dyi = f( dxi );

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

    // Define the strides:
    int64_t strides[] = { 1, 1, 8 }; // 1 byte per uint8, 8 bytes per double

    // Define the number of elements over which to iterate:
    int64_t shape[] = { 3 };

    // Apply the callback:
    stdlib_strided_mask_b_d_as_d_d( arrays, shape, strides, (void *)scale );
