Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var ns = require( '@skylernpm/voluptates-animi-consequatur' );

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.
• 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.
