{{alias}}( x, clbk[, thisArg] )
    Computes the midrange of an array via a callback function,
    ignoring NaN values.

    If provided an empty array, the function returns `NaN`.

    The callback function is provided three arguments:

    - value: current array element.
    - index: current array index.
    - array: the input array.

    The callback function should return a numeric value.

    If the callback function returns `NaN`, the value is ignored.

    If the callback function does not return any value (or equivalently,
    explicitly returns `undefined`), the value is ignored.

    Parameters
    ----------
    x: Array|TypedArray
        Input array.

    clbk: Function
        Callback function.

    thisArg: any (optional)
        Execution context.

    Returns
    -------
    out: number
        Midrange.

    Examples
    --------
    > function accessor( v ) { return v * 2.0; };
    > var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, NaN, -1.0, -3.0 ];
    > {{alias}}( x, accessor )
    -1.0
