clc,clear all

b0 = 0.015;

b1 = 0.015;

b2 = 0.035;

b3 = 0.050;

v = 40; %velocity

L = 2;

w = (2*pi*v)/L; %angular frequency

F = w*(1/(2*pi)); %in Hz

t = linspace(0,10,18);

b = b0 + b1*sin(w*t) + b2*sin(2*w*t)

+b3*sin(3*w*t);

plot(t,b)

Hi, I want to make this graph as being a smooth graph.

Thank you for your time.

You need to increase the step size of your t vector:

t = linspace(0,10,100);

Code:

b0 = 0.015;

b1 = 0.015;

b2 = 0.035;

b3 = 0.050;

v = 40; %velocity

L = 2;

w = (2*pi*v)/L; %angular frequency

F = w*(1/(2*pi)); %in Hz

t = linspace(0,10,100);

b = b0 + b1*sin(w*t)+b2*sin(2*w*t)+b3*sin(3*w*t);

plot(t,b)

t = linspace(0,10,18);

Increase the 18 to something larger, such as 50.
