## Usage
```javascript
var ns = require( '@stdlib/ndarray/iter' );
```
#### ns
Namespace containing utilities for iterating over multidimensional arrays.
```javascript
var o = ns;
// returns {...}
```
- [`nditerColumnEntries( x[, options] )`][@stdlib/ndarray/iter/column-entries]: create an iterator which returns `[index, column]` pairs for each column in a matrix (or stack of matrices).
- [`nditerColumns( x[, options] )`][@stdlib/ndarray/iter/columns]: create an iterator which iterates over each column in a matrix (or stack of matrices).
- [`nditerEntries( x[, options] )`][@stdlib/ndarray/iter/entries]: create an iterator which returns `[index, value]` pairs for each element in a provided `ndarray`.
- [`nditerIndices( shape[, options] )`][@stdlib/ndarray/iter/indices]: create an iterator which returns indices for use indexing into an `ndarray` having a specified shape.
- [`nditerInterleaveSubarrays( arr, ndims )`][@stdlib/ndarray/iter/interleave-subarrays]: create an iterator which iterates over interleaved subarrays.
- [`nditerMatrices( x[, options] )`][@stdlib/ndarray/iter/matrices]: create an iterator which iterates over each matrix in a stack of matrices.
- [`nditerMatrixEntries( x[, options] )`][@stdlib/ndarray/iter/matrix-entries]: create an iterator which returns `[index, matrix]` pairs for each matrix in a stack of matrices.
- [`nditerRowEntries( x[, options] )`][@stdlib/ndarray/iter/row-entries]: create an iterator which returns `[index, row]` pairs for each row in a matrix (or stack of matrices).

- [`nditerSelectDimension( x, dim[, options] )`][@stdlib/ndarray/iter/select-dimension]: create an iterator which iterates over each view along a specified dimension.
- [`nditerStacks( x, dims[, options] )`][@stdlib/ndarray/iter/stacks]: create an iterator which iterates over each subarray in a stack of subarrays according to a list of specified stack dimensions.
- [`nditerSubarrays( x, ndims[, options] )`][@stdlib/ndarray/iter/subarrays]: create an iterator which iterates over each subarray in a stack of subarrays.
- [`nditer2arrayEach( iterator )`][@stdlib/ndarray/iter/to-array-each]: create an iterator which converts each iterated `ndarray` to a generic array.
- [`nditerValues( x[, options] )`][@stdlib/ndarray/iter/values]: create an iterator which returns individual elements from a provided `ndarray`.
