{{alias}}( x[, options], predicate[, thisArg] )
    Tests whether at least one element along one or more ndarray dimensions
    passes a test implemented by a predicate function.

    Parameters
    ----------
    x: ndarray
        Input ndarray.

    options: Object (optional)
        Function options.

    options.dims: Array<integer> (optional)
        List of dimensions over which to perform a reduction. If not provided,
        the function performs a reduction over all elements in a provided input
        ndarray.

    options.keepdims: boolean (optional)
        Boolean indicating whether the reduced dimensions should be included in
        the returned ndarray as singleton dimensions. Default: false.

    predicate: Function
        Predicate function.

    thisArg: any (optional)
        Predicate function execution context.

    Returns
    -------
    out: ndarray
        Output ndarray. When performing a reduction over all elements, the
        function returns a zero-dimensional ndarray containing the result.

    Examples
    --------
    > var x = {{alias:@stdlib/ndarray/array}}( [ [ 1.0, -2.0 ], [ 3.0, -4.0 ] ] )
    <ndarray>
    > function f( v ) { return v > 0.0; };
    > var out = {{alias}}( x, f )
    <ndarray>[ true ]


{{alias}}.assign( x, y[, options], predicate[, thisArg] )
    Tests whether at least one element along one or more ndarray dimensions
    passes a test implemented by a predicate function and assigns the results to
    a provided output ndarray.

    Parameters
    ----------
    x: ndarray
        Input ndarray.

    y: ndarray
        Output ndarray. The output shape must match the shape of the non-reduced
        dimensions of the input ndarray.

    options: Object (optional)
        Function options.

    options.dims: Array<integer> (optional)
        List of dimensions over which to perform a reduction. If not provided,
        the function performs a reduction over all elements in a provided input
        ndarray.

    predicate: Function
        Predicate function.

    thisArg: any (optional)
        Predicate function execution context.

    Returns
    -------
    out: ndarray
        Output ndarray.

    Examples
    --------
    > var x = {{alias:@stdlib/ndarray/array}}( [ [ 1.0, -2.0 ], [ 3.0, -4.0 ] ] )
    <ndarray>
    > var y = {{alias:@stdlib/ndarray/empty}}( [], { 'dtype': 'bool' } )
    <ndarray>
    > function f( v ) { return v > 0.0; };
    > var out = {{alias}}.assign( x, y, f )
    <ndarray>[ true ]
    > var bool = ( y === out )
    true
