I want to control 3 dc motors with encoders so I have used simulink and arduino (3arduino boards)

I used matlab function block in simulink area for controlling method and for writting the voltage of the dc motors and for the reading the position and velocity of encoders

in fact I have used 3 matlab function but when I run the simulink it showed error the code that I have wriiten in matlab function to read the position and velocity is:

function [count1 count2 count3 speed1 speed2 speed3]=fcn
a1=arduino('com3','due','Libraries','RotaryEncoder');
a2=arduino('com5','uno','Libraries','RotaryEncoder');
a3=arduino('com6','uno','Libraries','RotaryEncoder');
encoder1=rotaryEncoder(a1,'D2','D3',4000);
encoder2=rotaryEncoder(a2,'D2','D3',4000);
encoder3=rotaryEncoder(a3,'D2','D3',48);
count1=readCount(encoder1);
speed1=readSpeed(enocder1);
count2=readCount(encoder2);
speed2=readSpeed(encoder2);
count3=readCount(encoder3);
speed3=readSpeed(encoder3);
end
