{{alias}}( shape, strides, offset, order, idx, mode )
Converts a linear index to an array of subscripts.
When provided a stride array containing negative strides, if an `offset` is
greater than `0`, the function interprets the linear index as an index into
the underlying data buffer for the array, thus returning subscripts from the
perspective of that buffer. If an `offset` is equal to `0`, the function
treats the linear index as an index into an array view, thus returning
subscripts from the perspective of that view. In short, from the perspective
of a view, view data is always ordered.
Parameters
----------
shape: ArrayLike
Array shape.
strides: ArrayLike
Stride array.
offset: integer
Location of the first indexed value based on the stride array.
order: string
Specifies whether an array is row-major (C-style) or column-major
(Fortran-style).
idx: integer
Linear index.
mode: string
Specifies how to handle a linear index which exceeds array dimensions.
If equal to 'throw', the function throws an error when a linear index
exceeds array dimensions. If equal to 'wrap', the function wraps around
a linear index exceeding array dimensions using modulo arithmetic. If
equal to 'clamp', the function sets a linear index exceeding array
dimensions to either `0` (minimum linear index) or the maximum linear
index. Default: 'throw'.
Returns
-------
out: Array
Subscripts.
Examples
--------
> var d = [ 3, 3, 3 ];
> var s = [ 9, 3, 1 ];
> var out = {{alias}}( d, s, 0, 'row-major', 17, 'throw' )
[ 1, 2, 2 ]
{{alias}}.assign( shape, strides, offset, order, idx, mode, out )
Converts a linear index to an array of subscripts and assigns results to a
provided output array.
When provided a stride array containing negative strides, if an `offset` is
greater than `0`, the function interprets the linear index as an index into
the underlying data buffer for the array, thus returning subscripts from the
perspective of that buffer. If an `offset` is equal to `0`, the function
treats the linear index as an index into an array view, thus returning
subscripts from the perspective of that view. In short, from the perspective
of a view, view data is always ordered.
Parameters
----------
shape: ArrayLike
Array shape.
strides: ArrayLike
Stride array.
offset: integer
Location of the first indexed value based on the stride array.
order: string
Specifies whether an array is row-major (C-style) or column-major
(Fortran-style).
idx: integer
Linear index.
mode: string
Specifies how to handle a linear index which exceeds array dimensions.
If equal to 'throw', the function throws an error when a linear index
exceeds array dimensions. If equal to 'wrap', the function wraps around
a linear index exceeding array dimensions using modulo arithmetic. If
equal to 'clamp', the function sets a linear index exceeding array
dimensions to either `0` (minimum linear index) or the maximum linear
index. Default: 'throw'.
out: Array|TypedArray|Object
Output object.
Returns
-------
out: Array|TypedArray|Object
Subscripts.
Examples
--------
> var d = [ 3, 3, 3 ];
> var s = [ 9, 3, 1 ];
> var out = [ 0, 0, 0 ];
> var sub = {{alias}}.assign( d, s, 0, 'row-major', 17, 'throw', out )
[ 1, 2, 2 ]
> var bool = ( sub === out )
true
