If not provided, the function performs the operation over all elements in a provided input [ndarray][@stdlib/ndarray/ctor]. + +
+ + + +
+ +## Notes + +- Both functions iterate over [ndarray][@stdlib/ndarray/ctor] elements according to the memory layout of the input [ndarray][@stdlib/ndarray/ctor]. Accordingly, performance degradation is possible when operating over multiple dimensions of a large non-contiguous multi-dimensional input [ndarray][@stdlib/ndarray/ctor]. In such scenarios, one may want to copy an input [ndarray][@stdlib/ndarray/ctor] to contiguous memory before performing the operation. +- The output data type [policy][@stdlib/ndarray/output-dtype-policies] only applies to the main function and specifies that, by default, the function must return an [ndarray][@stdlib/ndarray/ctor] having a boolean or "generic" [data type][@stdlib/ndarray/dtypes]. For the `assign` method, the output [ndarray][@stdlib/ndarray/ctor] is allowed to have any supported output [data type][@stdlib/ndarray/dtypes]. +- Both functions explicitly treat `NaN` values as falsy. + +
+ + + +
+ +## Examples + + + +```javascript +var bernoulli = require( '@stdlib/random/bernoulli' ); +var getDType = require( '@stdlib/ndarray/dtype' ); +var ndarray2array = require( '@stdlib/ndarray/to-array' ); +var cunone = require( '@stdlib/blas/ext/cunone' ); + +// Generate an ndarray of random numbers: +var x = bernoulli( [ 5, 5 ], 0.3, { + 'dtype': 'generic' +}); +console.log( ndarray2array( x ) ); + +// Perform operation: +var y = cunone( x, { + 'dims': [ 0 ] +}); + +// Resolve the output array data type: +var dt = getDType( y ); +console.log( dt ); + +// Print the results: +console.log( ndarray2array( y ) ); +``` + +
