I keep getting this error message when trying to run my code, I'm confident my wiring is correct and I do not know what this error means-

Library 'Servo' is not uploaded to the board. Clear the current Arduino object and recreate it to include the appropriate library. For a list of available libraries, type 'listArduinoLibraries'.

here is my code

a=arduino();
s1 = servo(a, 'D9', 'MinPulseDuration', 700*10^-6, 'MaxPulseDuration', 2300*10^-6);
writePosition(s1,0);
userResponse = "yes";
while userResponse == "yes"
chicken = input("Insert your resistor");
voltage = readVoltage(a, "A0");
    if voltage < 1.67155
        resistor = "47k";
        writePosition(s1,0.25);
        minR = 47000 * 0.95;
        maxR = 47000 * 1.05;
    elseif voltage < 3.53128
        resistor = "10k";
        writePosition(s1,0.5);
        minR = 10000 * 0.95;
        maxR = 10000 * 1.05;
    elseif voltage < 4.69941
        resistor = "1k";
        writePosition(s1,0.75);
        minR = 1000 * 0.95;
        maxR = 1000 * 1.05;
    else
        resistor = "330";
        writePosition(s1,1);
        minR = 330 * 0.95;
        maxR = 330 * 1.05;
    end
resistance = voltageToResistance(voltage);
withinTolerance = (resistance >= minR && resistance <= maxR);
disp(resistor)
if withinTolerance == 1
    writeDigitalPin(a, "D4", 1);
    writeDigitalPin(a, "D5", 0);
    %disp("green")
else 
    writeDigitalPin(a, "D4", 0);
    writeDigitalPin(a, "D5", 1);
    %disp("Red")
end
userResponse = input("Would you like to check another resistor? ","s");
writePosition(s1,0);
writeDigitalPin(a, "D4", 0);
writeDigitalPin(a, "D5", 0);
end
