ndarray

Multidimensional arrays.

Usage

var ns = require( '@stdlib/ndarray' );

ns

ndarray namespace.

var o = ns;
// returns {...}

The namespace exports the following functions to create multidimensional arrays:

• array( [buffer,] [options] ): create a multidimensional array.
• ndarray( dtype, buffer, shape, strides, offset, order[, options] ): multidimensional array constructor.

The namespace contains the following sub-namespaces:

• base: base ndarray.
• iter: multidimensional array iterators.

In addition, the namespace contains the following multidimensional array utility functions:

• at( x[, ...indices] ): return an ndarray element.
• broadcastArray( x, shape ): broadcast an ndarray to a specified shape.
• broadcastArrays( ...arrays ): broadcast ndarrays to a common shape.
• castingModes(): list of ndarray casting modes.
• dataBuffer( x ): return the underlying data buffer of a provided ndarray.
• defaults(): default ndarray settings.
• dispatch( fcns, types, data, nargs, nin, nout ): create an ndarray function interface which performs multiple dispatch.
• dtype( x ): return the data type of a provided ndarray.
• dtypes( [kind] ): list of ndarray data types.
• emptyLike( x[, options] ): create an uninitialized ndarray having the same shape and data type as a provided ndarray.
• empty( shape[, options] ): create an uninitialized ndarray having a specified shape and data type.
• FancyArray( dtype, buffer, shape, strides, offset, order[, options] ): fancy multidimensional array constructor.
• filterMap( x[, options], fcn[, thisArg] ): filter and map elements in an input ndarray to elements in a new output ndarray according to a callback function.
• filter( x[, options], predicate[, thisArg] ): return a shallow copy of an ndarray containing only those elements which pass a test implemented by a predicate function.
• flag( x, name ): return a specified flag for a provided ndarray.
• flags( x ): return the flags of a provided ndarray.
• forEach( x, fcn[, thisArg] ): invoke a callback function once for each ndarray element.
• scalar2ndarray( value[, options] ): convert a scalar value to a zero-dimensional ndarray.
• ind2sub( shape, idx[, options] ): convert a linear index to an array of subscripts.
• indexModes(): list of ndarray index modes.
• ndindex( x[, options] ): ndarray index constructor.
• map( x[, options], fcn[, thisArg] ): apply a callback function to elements in an input ndarray and assign results to elements in a new output ndarray.
• maybeBroadcastArray( x, shape ): broadcast an ndarray to a specified shape if and only if the specified shape differs from the provided ndarray's shape.
• maybeBroadcastArrays( arrays ): broadcast ndarrays to a common shape.
• minDataType( value ): determine the minimum ndarray data type of the closest "kind" necessary for storing a provided scalar value.
• mostlySafeCasts( [dtype] ): return a list of ndarray data types to which a provided ndarray data type can be safely cast and, for floating-point data types, can be downcast.
• ndarraylike2ndarray( x[, options] ): convert an ndarray-like object to an ndarray.
• ndims( x ): return the number of ndarray dimensions.
• nextDataType( [dtype] ): return the next larger ndarray data type of the same kind.
• numelDimension( x, dim ): return the size (i.e., number of elements) of a specified dimension for a provided ndarray.
• numel( x ): return the number of elements in an ndarray.
• offset( x ): return the index offset specifying the underlying buffer index of the first iterated ndarray element.
• order( x ): return the layout order of a provided ndarray.
• orders(): list of ndarray orders.
• outputDataTypePolicies(): list of output ndarray data type policies.
• promotionRules( [dtype1, dtype2] ): return the ndarray data type with the smallest size and closest "kind" to which ndarray data types can be safely cast.
• reject( x[, options], predicate[, thisArg] ): return a shallow copy of an ndarray containing only those elements which fail a test implemented by a predicate function.
• safeCasts( [dtype] ): return a list of ndarray data types to which a provided ndarray data type can be safely cast.
• sameKindCasts( [dtype] ): return a list of ndarray data types to which a provided ndarray data type can be safely cast or cast within the same "kind".
• shape( x ): return the shape of a provided ndarray.
• sliceAssign( x, y, ...s[, options] ): assign element values from a broadcasted input ndarray to corresponding elements in an output ndarray view.
• sliceDimensionFrom( x, dim, start[, options] ): return a read-only shifted view of an input ndarray along a specified dimension.
• sliceDimensionTo( x, dim, stop[, options] ): return a read-only truncated view of an input ndarray along a specified dimension.
