This function takes into account ndarray-like objects which may support index modes.\n*\n* - This function defaults to returning cached serialized meta data.

If the endianness is `0`, the byte order is big endian.\n*\n* - Buffer length:\n*\n* ```text\n* 1 + 2 + 8 + (ndims*8) + (ndims*8) + 8 + 1 + 1 + 8 + (nsubmodes*1) + 4 = 33 + (ndims*16) + nsubmodes\n* ```\n*\n* For example, consider a three-dimensional ndarray with one subscript index mode (submode):\n*\n* ```text\n* 33 + (3*16) + 1 = 82 bytes\n* ```\n*\n* - Views:\n*\n* - endianness: `Int8Array(

This function takes into account ndarray-like objects which may support index modes.\n*\n* - This function defaults to returning cached serialized meta data.

If the endianness is `0`, the byte order is big endian.\n*\n* - Buffer length:\n*\n* ```text\n* 1 + 2 + 8 + (ndims*8) + (ndims*8) + 8 + 1 + 1 + 8 + (nsubmodes*1) + 4 = 33 + (ndims*16) + nsubmodes\n* ```\n*\n* For example, consider a three-dimensional ndarray with one subscript index mode (submode):\n*\n* ```text\n* 33 + (3*16) + 1 = 82 bytes\n* ```\n*\n* - Views:\n*\n* - endianness: `Int8Array(

provided ndarray. -* - If a provided ndarray has a different (broadcast compatible) shape than the specified shape, the function returns a new (base) ndarray view of the provided ndarray's data. The view is typically **not** contiguous. As more than one element of a returned view may refer to the same memory location, writing to the view may affect multiple elements. If you need to write to the returned array, copy the array before performing operations which may mutate elements. -* -* @param {ndarray} arr - input array -* @param {NonNegativeIntegerArray} shape - desired shape -* @throws {Error} input array cannot have more dimensions than the desired shape -* @throws {Error} input array dimension sizes must be `1` or equal to the corresponding dimension in the provided shape -* @throws {Error} input array and desired shape must be broadcast compatible -* @returns {ndarray} broadcasted array -* -* @example -* var array = require( '@stdlib/ndarray-array' ); -* -* var x = array( [ [ 1, 2 ], [ 3, 4 ] ] ); -* // returns -* -* var shx = x.shape; -* // returns [ 2, 2 ] -* -* var y = maybeBroadcastArray( x, [ 3, 2, 2 ] ); -* // returns -* -* var shy = y.shape; -* // returns [ 3, 2, 2 ] -* -* var v = y.get( 0, 0, 0 ); -* // returns 1 -* -* v = y.get( 0, 0, 1 ); -* // returns 2 -* -* v = y.get( 1, 0, 0 ); -* // returns 1 -* -* v = y.get( 1, 1, 0 ); -* // returns 3 -* -* v = y.get( 2, 0, 0 ); -* // returns 1 -* -* v = y.get( 2, 1, 1 ); -* // returns 4 -* -* @example -* var array = require( '@stdlib/ndarray-array' ); -* -* var x = array( [ [ 1, 2 ], [ 3, 4 ] ] ); -* // returns -* -* var y = maybeBroadcastArray( x, [ 3, 2 ] ); -* // throws -*/ -function maybeBroadcastArray( arr, shape ) { - var sh; - var N; - var i; - - N = shape.length; - sh = getShape( arr, false ); - - // Check whether we need to broadcast the input array... - if ( sh.length === N ) { - for ( i = 0; i < N; i++ ) { - // Check whether dimensions match... - if ( sh[ i ] !== shape[ i ] ) { - // We found a mismatched dimension; delegate to `broadcast` to ensure that the input array is broadcast compatible with the desired array shape... - return broadcast( arr, shape ); - } - } - return arr; - } - // If we are provided an array having a different rank (i.e., number of dimensions) than the desired shape, assume we need to broadcast, delegating to `broadcast` to ensure that the input array is broadcast compatible with the desired array shape... - return broadcast( arr, shape ); -} - - -// EXPORTS // - -module.exports = maybeBroadcastArray; diff --git a/package.json b/package.json index a41389b..eeaf2a2 100644 --- a/package.json +++ b/package.json @@ -3,31 +3,7 @@ "version": "0.2.3", "description": "Broadcast an ndarray to a specified shape if and only if the specified shape differs from the provided ndarray's shape.", "license": "Apache-2.0", - "author": { - "name": "The Stdlib Authors", - "url": "https://github.com/stdlib-js/stdlib/graphs/contributors" - }, - "contributors": [ - { - "name": "The Stdlib Authors", - "url": "https://github.com/stdlib-js/stdlib/graphs/contributors" - } - ], - "main": "./lib", - "directories": { - "benchmark": "./benchmark", - "doc": "./docs", - "example": "./examples", - "lib": "./lib", - "test": "./test" - }, - "types": "./docs/types", - "scripts": { - "test": "make test", - "test-cov": "make test-cov", - "examples": "make examples", - "benchmark": "make benchmark" - }, + "main": "./index.js", "homepage": "https://stdlib.io", "repository": { "type": "git", @@ -36,39 +12,6 @@ "bugs": { "url": "https://github.com/stdlib-js/stdlib/issues" }, - "dependencies": { - "@stdlib/ndarray-base-broadcast-array": "^0.2.2", - "@stdlib/ndarray-base-shape": "^0.2.2", - "@stdlib/types": "^0.4.3" - }, - "devDependencies": { - "@stdlib/array-float64": "^0.2.2", - "@stdlib/assert-is-ndarray-like": "^0.2.2", - "@stdlib/ndarray-array": "^0.2.1", - "@stdlib/ndarray-base-ctor": "^0.2.2", - "@stdlib/ndarray-base-numel": "^0.2.2", - "@stdlib/ndarray-ctor": "^0.2.2", - "@stdlib/ndarray-ind2sub": "^0.2.2", - "tape": "git+https://github.com/kgryte/tape.git#fix/globby", - "istanbul": "^0.4.1", - "tap-min": "git+https://github.com/Planeshifter/tap-min.git", - "@stdlib/bench-harness": "^0.2.2" - }, - "engines": { - "node": ">=0.10.0", - "npm": ">2.7.0" - }, - "os": [ - "aix", - "darwin", - "freebsd", - "linux", - "macos", - "openbsd", - "sunos", - "win32", - "windows" - ], "keywords": [ "stdlib", "stdtypes", @@ -85,7 +28,6 @@ "utils", "util" ], - "__stdlib__": {}, "funding": { "type": "opencollective", "url": "https://opencollective.com/stdlib" diff --git a/stats_browser.html b/stats_browser.html new file mode 100644 index 0000000..46d89a1 --- /dev/null +++ b/stats_browser.html @@ -0,0 +1,4842 @@ + + + + + + + + Rollup Visualizer + + + +
