Cannot use 'device' function to work via I2C communication. -MATLAB

I want to use MPU 6050 to send data to MATLAB.

But there is an error => Undefined function or variable 'device'.

I am using MATLAB R2019a academic use, already have Instrument control toolbox.

The code I used =>

%% setup 
clear all
hold all
a = arduino;
mpu = device (a, 'I2CAddress' , '0x68' ); % mpu adress is normally 0x68
writeRegister (mpu, hex2dec ( 'B6' ), hex2dec ('00 ' ), ' int16 ' ); % reset
data = zeros (10000,14, 'int8' ); % prelocating for the speed
j = 1;
a1 = animatedline ( 'Color' , [1 0 0]);
a2 = animatedline ( 'Color' , [0 1 0]);
a3 = animatedline ( 'Color' , [0 0 1]);
legend ( 'Accel_x' , 'Accel_y' , 'Accel_z' )
%% loop
while (true)
    x = 1;
    for i = 59: 72 % 14 Data Registers for Accel, Temp, Gyro
        data (j, x) = readRegister (mpu, i, 'int8' );
        x = x + 1;
    end
    y = swapbytes (typecast (data (j, :), 'int16' )) % if your system is big-endian remove the swapbytes function
    addpoints (a1, j, double (y (1)));
    addpoints (a2, j, double (y (2)));
    addpoints (a3, j, double (y (3)));
    j = j + 1;
    drawnow limitrate
end
