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: fgt_get_sensorBypassValve.m
    path of file: ./repos/fgt-SDK/MATLAB/Toolbox/SDK/Fluigent
    
    the code of the file until where you have to start completion: function [state, error_code] = fgt_get_sensorBypassValve( sensorIndex )

    
function [state, error_code] = fgt_get_sensorBypassValve( sensorIndex )
%FGT_GET_SENSORBYPASSVALVE Get the state of the sensor's bypass valve.
% 
% This feature is only available on NIFS devices.
%
% state = fgt_get_sensorBypassValve( sensorIndex ) returns 0 if the sensor's 
% bypass valve is closed and 1 if it is open.
%
% [state, error_code] = fgt_get_sensorBypassValve( sensorIndex ) also
% returns the error code returned by the library function

[error_code, state] = LowLevel.fgt_get_sensorBypassValve(sensorIndex);
manage_sensor_status('fgt_get_sensorBypassValve', sensorIndex);
error_code = fgt_ERROR_CODE(error_code);
end
