Hi Dear all i want to make a trajectory path which i have done but i am unable to get the output in simulink please help me fast what mistake i am doing????
T=20;
a0 = theta0;
a2 = (-3 * (theta0 - thetaf) - (2 * thetad0+thetadf )*T)/ T ^ 2;
a3 = (2 * (theta0 - thetaf) + (thetad0+thetadf )*T)/ T ^ 3;
end
p=[a3 ,a2 , a1 , a0];
t=linspace(0,20,100);
Pos=polyval(p,t)
plot(t,Pos)
This give me nice result but i want the Pos my output in simulink

You can use From Workspace block to transfer trajectory signal data from MATLAB base workspace to Simulink.

I have already done that but unable to get that Well I am not a newbie to matlab I know all these basics Please provide me some example

Here is a simple example demonstrating how to use From Workspace to get base workspace data in Simulink.
First, run this code to create sample data:
t = 0:0.1:10;
y = t.^2;
data = [t' y'];
Then run the attached Simulink model. Also check the setting of the From Workspace block to see how to set the variable name.

Right-click on the file name and press Save Link as. Also instead of starting a new answer, it is better to keep comment on the original answer. It helps keep track of the things.
