+# reject
+
+> Return a shallow copy of an [ndarray][@stdlib/ndarray/ctor] containing only those elements which fail a test implemented by a predicate function.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var reject = require( '@stdlib/ndarray/reject' );
+```
+
+#### reject( x\[, options], predicate\[, thisArg] )
+
+Returns a shallow copy of an [ndarray][@stdlib/ndarray/ctor] containing only those elements which fail a test implemented by a `predicate` function.
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var ndarray = require( '@stdlib/ndarray/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+
+function predicate( z ) {
+ return z <= 6.0;
+}
+
+var buffer = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] );
+var shape = [ 2, 3 ];
+var strides = [ 6, 1 ];
+var offset = 1;
+
+var x = ndarray( 'float64', buffer, shape, strides, offset, 'row-major' );
+// returns
+
+var y = reject( x, predicate );
+// returns
+
+var arr = ndarray2array( y );
+// returns [ 8.0, 9.0, 10.0 ]
+```
+
+The function accepts the following arguments:
+
+- **x**: input [ndarray][@stdlib/ndarray/ctor].
+- **options**: function options.
+- **predicate**: predicate function.
+- **thisArg**: predicate function execution context.
+
+The function accepts the following options:
+
+- **dtype**: output ndarray [data type][@stdlib/ndarray/dtypes]. If not specified, the output ndarray [data type][@stdlib/ndarray/dtypes] is inferred from the input [ndarray][@stdlib/ndarray/ctor].
+- **order**: index iteration order. By default, the function iterates over elements according to the [layout order][@stdlib/ndarray/orders] of the provided [ndarray][@stdlib/ndarray/ctor]. Accordingly, for row-major input [ndarrays][@stdlib/ndarray/ctor], the last dimension indices increment fastest. For column-major input [ndarrays][@stdlib/ndarray/ctor], the first dimension indices increment fastest. To override the inferred order and ensure that indices increment in a specific manor, regardless of the input [ndarray][@stdlib/ndarray/ctor]'s layout order, explicitly set the iteration order. Note, however, that iterating according to an order which does not match that of the input [ndarray][@stdlib/ndarray/ctor] may, in some circumstances, result in performance degradation due to cache misses. Must be either `'row-major'` or `'column-major'`.
+
+By default, the output ndarray [data type][@stdlib/ndarray/dtypes] is inferred from the input [ndarray][@stdlib/ndarray/ctor]. To return an ndarray with a different [data type][@stdlib/ndarray/dtypes], specify the `dtype` option.
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var ndarray = require( '@stdlib/ndarray/ctor' );
+var dtype = require( '@stdlib/ndarray/dtype' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+
+function predicate( z ) {
+ return z <= 6.0;
+}
+
+var buffer = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] );
+var shape = [ 2, 3 ];
+var strides = [ 6, 1 ];
+var offset = 1;
+
+var x = ndarray( 'float64', buffer, shape, strides, offset, 'row-major' );
+// returns
+
+var opts = {
+ 'dtype': 'float32'
+};
+var y = reject( x, opts, predicate );
+// returns
+
+var dt = dtype( y );
+// returns 'float32'
+
+var arr = ndarray2array( y );
+// returns [ 8.0, 9.0, 10.0 ]
+```
+
+The `predicate` function is provided the following arguments:
+
+- **value**: current array element.
+- **indices**: current array element indices.
+- **arr**: the input [ndarray][@stdlib/ndarray/ctor].
+
+
+
+
+
+
+
+## Notes
+
+- The function does **not** perform explicit casting (e.g., from a real-valued floating-point number to a complex floating-point number). Any such casting should be performed **prior to** calling this function.
+- The function **always** returns a one-dimensional [ndarray][@stdlib/ndarray/ctor].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var naryFunction = require( '@stdlib/utils/nary-function' );
+var array = require( '@stdlib/ndarray/array' );
+var isPositive = require( '@stdlib/assert/is-positive-number' ).isPrimitive;
+var reject = require( '@stdlib/ndarray/reject' );
+
+var buffer = discreteUniform( 10, -100, 100, {
+ 'dtype': 'generic'
+});
+var x = array( buffer, {
+ 'shape': [ 5, 2 ],
+ 'dtype': 'generic'
+});
+console.log( ndarray2array( x ) );
+
+var y = reject( x, naryFunction( isPositive, 1 ) );
+console.log( ndarray2array( y ) );

+{{alias}}( x[, options], predicate[, thisArg] )
+ Returns a shallow copy of an ndarray containing only those elements which
+ fail a test implemented by a predicate function.
+
+ The predicate function is provided the following arguments:
+
+ - value: current array element.
+ - indices: current array element indices.
+ - arr: the input ndarray.
+
+ Parameters
+ ----------
+ x: ndarray
+ Input ndarray.
+
+ options: Object (optional)
+ Function options.
+
+ options.dtype: string (optional)
+ Output ndarray data type. Overrides using the input array's inferred
+ data type.
+
+ options.order: string (optional)
+ Index iteration order. By default, the function iterates over elements
+ according to the layout order of the provided array. Accordingly, for
+ row-major input arrays, the last dimension indices increment fastest.
+ For column-major input arrays, the first dimension indices increment
+ fastest. To override the inferred order and ensure that indices
+ increment in a specific manor, regardless of the input array's layout
+ order, explicitly set the iteration order. Note, however, that iterating
+ according to an order which does not match that of the input array may,
+ in some circumstances, result in performance degradation due to cache
+ misses. Must be either 'row-major' or 'column-major'.
+
+ predicate: Function
+ Predicate function.
+
+ thisArg: any (optional)
+ Predicate function execution context.
+
+ Examples
+ --------
+ > var x = {{alias:@stdlib/ndarray/array}}( [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ] );
+ > function f( v ) { return v <= 2.0; };
+ > var y = {{alias}}( x, f );
+ > {{alias:@stdlib/ndarray/to-array}}( y )
