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.
flag( x, name ): return a specified flag for a provided ndarray.
flags( x ): return the flags of a provided ndarray.
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.
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.
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.
sliceDimension( x, dim, slice[, options] ): return a read-only view of an input ndarray when sliced along a specified dimension.
sliceFrom( x, ...start[, options] ): return a read-only shifted view of an input ndarray.
sliceTo( x, ...stop[, options] ): return a read-only truncated view of an input ndarray.
slice( x, ...s[, options] ): return a read-only view of an input ndarray.
stride( x, dim ): return the stride along a specified dimension for a provided ndarray.
strides( x ): return the strides of a provided ndarray.
sub2ind( shape, ...subscripts[, options] ): convert subscripts to a linear index.
ndarray2array( x ): convert an ndarray to a generic array.
zerosLike( x[, options] ): create a zero-filled ndarray having the same shape and data type as a provided ndarray.
zeros( shape[, options] ): create a zero-filled ndarray having a specified shape and data type.
