You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: adimat_aio_init.m
    path of file: ./repos/d2d/arFramework3/ThirdParty/StrucID/adimat/runtime
    
    the code of the file until where you have to start completion: % function r = adimat_aio_init(nThreads?, nBuffers?, idleTime?, direct?)
%
% get/set some parameters of the aio.h API. This functionality is
% implemented by setting the environment variables AIO_THREADS,
% AIO_NUM, and AIO_IDLE_TIME, respectively. The variable's values are
% used to call the non standard function aio_init, which is available
% e.g. on GNU implementations. These settings apply only to those
% stack implementations with "abuffered" in their name.
%
% adimat_aio_init(nThreads, nBuffers?, idleTime?, oDirect?)
%   - this sets the parameters

% adimat_aio_init(nThreads, nBuffers?, idleTime?, oDirect?)
%   - this sets the parameters
%
% adimat_aio_init()
%   - this returns the values that are currently set in a cell array
%
% adimat_aio_init('clear')
%   - clear all four variables
%
% Parameters can either be float scalars or empty, in which case the
% default values will be used. The default value for AIO_THREADS and
% AIO_NUM is ADIMAT_STACK_NUM_BUFFERS, the default for AIO_IDLE_TIME
% is 10, and the default for ABUF_ODIRECT is 0 (off).
