Hello! I am having trouble plotting my graph. Here is my code. It shows the graph but nothing is plotting. Any idea what is happening? Please let me know! Thank you
xlabel('Time')
ylabel('Thrust')
title('Thrust Varying With Time')
x = linspace(0,0.001,1);
y = linspace(0,5,500);
A = (pi*(.021336)^2)/4;
Po = 400000;
Patm = 101325;
f(x)= (2*(Po-Patm)*A)*x;
plot (x,f(x))

The left side of the line
f(x)= (2*(Po-Patm)*A)*x;
is not correct. f(x) represent indexing into f using x vector, which is only allowed if all values in x are integers. You don't need that here. Check this code
x = linspace(0,0.001,100);
A = (pi*(.021336)^2)/4;
Po = 400000;
Patm = 101325;
f = (2*(Po-Patm)*A)*x;
plot(x, f)

Hello, I am plotting a root locus graph based on the following code:
num=[1];
den=[1 3 0];
sys=tf(num,den)
rlocus(sys)
My plot appears but empty. No data.
