Must be a numeric or "generic" [data type][@stdlib/ndarray/dtypes]. Default: `'float64'`. +- **order**: specifies whether an [ndarray][@stdlib/ndarray/ctor] is `'row-major'` (C-style) or `'column-major'` (Fortran-style). Default: `'row-major'`. +- **mode**: specifies how to handle indices which exceed array dimensions (see [`ndarray`][@stdlib/ndarray/ctor]). Default: `'throw'`. +- **submode**: a mode array which specifies for each dimension how to handle subscripts which exceed array dimensions (see [`ndarray`][@stdlib/ndarray/ctor]). If provided fewer modes than dimensions, the function recycles modes using modulo arithmetic. Default: `[ options.mode ]`. + +By default, the function generates values along the last dimension of an output [ndarray][@stdlib/ndarray/ctor].

Must have a numeric or "generic" [data type][@stdlib/ndarray/dtypes]. +- **options**: function options (_optional_). + +The function accepts the following options: + +- **dims**: list of dimensions over which to perform operation. If not provided, the function generates values along the last dimension. Default: `[-1]`. + +
+ + + +
+ +## Notes + +- The function iterates 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. + +
+ + + +
+ +## Examples + + + +```javascript +var ndarray2array = require( '@stdlib/ndarray/to-array' ); +var zeroTo = require( '@stdlib/blas/ext/zero-to' ); + +// Create a new ndarray: +var x = zeroTo( [ 5, 5 ], { + 'dtype': 'generic' +}); +console.log( ndarray2array( x ) ); + +// Generate values over a specific dimension: +x = zeroTo( [ 5, 5 ], { + 'dtype': 'generic', + 'dims': [ 0 ] +}); +console.log( ndarray2array( x ) ); + +// Generate values over all dimensions: +x = zeroTo( [ 5, 5 ], { + 'dtype': 'generic', + 'dims': [ 0, 1 ] +}); +console.log( ndarray2array( x ) ); +``` + +
