Official document reference

fplot(@(x) sin(x))

xt = @(t) cos(3*t);
yt = @(t) sin(2*t);
fplot(xt,yt)

fplot(@(x) exp(x),[-3 0],'b')
hold on
fplot(@(x) cos(x),[0 3],'b')
hold off
grid on

Specify line properties

fplot(@(x) sin(x+pi/5),'Linewidth',2);
hold on
fplot(@(x) sin(x-pi/5),'--or');
fplot(@(x) sin(x),'-.*c')
hold off

fplot(@sin,[-2*pi 2*pi])
grid on

xlabel('x');
ylabel('y');

fplot The input must be one or more functions containing a single variable , Just a symbolic function , You don't have to handle functions
