{{alias}}( [buffer,] [options] ) Returns a multidimensional array. Parameters ---------- buffer: Array|TypedArray|Buffer|ndarray (optional) Data source. options: Object (optional) Options. options.buffer: Array|TypedArray|Buffer|ndarray (optional) Data source. If provided along with a `buffer` argument, the argument takes precedence. options.dtype: string (optional) Underlying storage data type. If not specified and a data source is provided, the data type is inferred from the provided data source. If an input data source is not of the same type, this option specifies the data type to which to cast the input data. For non-ndarray generic array data sources, the function casts generic array data elements to the default data type. In order to prevent this cast, the `dtype` option must be explicitly set to `'generic'`. Any time a cast is required, the `copy` option is set to `true`, as memory must be copied from the data source to an output data buffer. Default: 'float64'. options.order: string (optional) Specifies the memory layout of the data source as either row-major (C- style) or column-major (Fortran-style). The option may be one of the following values: - 'row-major': the order of the returned array is row-major. - 'column-major': the order of the returned array is column-major. - 'any': if a data source is column-major and not row-major, the order of the returned array is column-major; otherwise, the order of the returned array is row-major. - 'same': the order of the returned array matches the order of an input data source. Note that specifying an order which differs from the order of a provided data source does *not* entail a conversion from one memory layout to another. In short, this option is descriptive, not prescriptive. Default: 'row-major'. options.shape: Array (optional) Array shape (dimensions). If a shape is not specified, the function attempts to infer a shape based on a provided data source. For example, if provided a nested array, the function resolves nested array dimensions. If provided a multidimensional array data source, the function uses the array's associated shape. For most use cases, such inference suffices. For the remaining use cases, specifying a shape is necessary. For example, provide a shape to create a multidimensional array view over a linear data buffer, ignoring any existing shape meta data associated with a provided data source. options.flatten: boolean (optional) Boolean indicating whether to automatically flatten generic array data sources. If an array shape is not specified, the shape is inferred from the dimensions of nested arrays prior to flattening. If a use case requires partial flattening, partially flatten prior to invoking this function and set the option value to `false` to prevent further flattening during invocation. Default: true. options.copy: boolean (optional) Boolean indicating whether to (shallow) copy source data to a new data buffer. The function does *not* perform a deep copy. To prevent undesired shared changes in state for generic arrays containing objects, perform a deep copy prior to invoking this function. Default: false. options.ndmin: integer (optional) Specifies the minimum number of dimensions. If an array shape has fewer dimensions than required by `ndmin`, the function prepends singleton dimensions to the array shape in order to satisfy the dimensions requirement. Default: 0. options.casting: string (optional) Specifies the casting rule used to determine acceptable casts. The option may be one of the following values: - 'none': only allow casting between identical types. - 'equiv': allow casting between identical and byte swapped types. - 'safe': only allow "safe" casts. - 'same-kind': allow "safe" casts and casts within the same kind (e.g., between signed integers or between floats). - 'unsafe': allow casting between all types (including between integers and floats). Default: 'safe'. options.codegen: boolean (optional) Boolean indicating whether to use code generation. Code generation can boost performance, but may be problematic in browser contexts enforcing a strict content security policy (CSP). Default: true. options.mode: string (optional) Specifies how to handle indices which exceed array dimensions. The option may be one of the following values: - 'throw': an ndarray instance throws an error when an index exceeds array dimensions. - 'wrap': an ndarray instance wraps around indices exceeding array dimensions using modulo arithmetic. - 'clamp', an ndarray instance sets an index exceeding array dimensions to either `0` (minimum index) or the maximum index. Default: 'throw'. options.submode: Array (optional) Specifies how to handle subscripts which exceed array dimensions. If a mode for a corresponding dimension is equal to - 'throw': an ndarray instance throws an error when a subscript exceeds array dimensions. - 'wrap': an ndarray instance wraps around subscripts exceeding array dimensions using modulo arithmetic. - 'clamp': an ndarray instance sets a subscript exceeding array dimensions to either `0` (minimum index) or the maximum index. If the number of modes is fewer than the number of dimensions, the function recycles modes using modulo arithmetic. Default: [ options.mode ]. Returns ------- out: ndarray Multidimensional array.
