getting error while plotting graph
显示 更早的评论
i want to plot graph between F and x
F=c*(|v|^n)*sgn(v)
and v is derivative of x w.r.t time
|v| is magnitude of v
here v is velocity, x is displacement
c is a constant and can be assumed 1
n ranges [0,2]
when i am plotting the graph is coming out wrong

and insert the code that is used to plot the graph. Also describe the expected trajectory to be observed on the graph.

Update: I have established the relationship between displacement and velocity using trigonometric functions, specifically sine and cosine, since 
.
.t = linspace(0, 1, 10001);
x = sin(2*pi*t); % displacement
v = cos(2*pi*t); % rate of displacement
c = 1;
n = 0:0.25:2;
for j = 1:length(n)
F = c*(abs(v).^n(j)).*sign(v);
plot(x, F), hold on, grid on, xlabel('x'), ylabel('F');
end
hold off
Previously: No information about the displacement, x, has been provided. If you provide x, I will revise the answer. Alternatively, I can also provide a simple motion system example if you wish. The absolute surd function (a.k.a. Absurd fcn) is plotted below:
vv = linspace(-1, 1, 20001);
cc = 1;
nn = 0.25;
FF = cc*(abs(vv).^nn).*sign(vv);
plot(vv, FF), grid on
xlabel('v'), ylabel('F')
