You need to install the support package, which can be done from R2014b onwards. See http://www.mathworks.com/help/supportpkg/arduinoio/setup-and-configuration.html

在 MATLAB Online 中打开

its working okay, thanks.

function [] = ServoAngle(Theta1,Theta2)
% gwnies apo 0-180;
Theta1=0:0.1:1;
Theta2=0:0.1:1;
L1=0.065;%m
L2=0.125;%m
a=arduino('COM4');
s = servo(a,9,'MinPulseDuration',7.50e-4,'MaxPulseDuration',2.4e-3);
s = servo(a,10,'MinPulseDuration',7.50e-4,'MaxPulseDuration',2.4e-3);
px=L2*cos(Theta1+Theta2) + L1*cos(Theta1)
py=L2*sin(Theta1+Theta2) + L1*sin(Theta1)
a.servoWrite(9,Theta1);
a.servoWrite(10,Theta2);
plot(px,py,'r.');
xlabel('Px','fontsize',10);
ylabel('Py','fontsize',10);
pause(1);
end
