check where is my error of command...

[awanis]

can anybody cek my command matlab..
i want to plot X(t) signal..

ts= 0.0313
y=linspace(0,4*pi,200);
x1=6*sin(3*pi*ts);
figure(4);
plot(y,x1,'r')
hold on
x2=[5*cos(6*pi*ts)];
plot(y,x2,'g')
x3=[7*cos(8*pi*ts+(0.167*pi))];
plot(y,x3,'-')
hold off

the error is at plot(y,x1,'r')..
what should i do with the command..

 

[Aya2002]

your ts must be a vector such as
ts=0:0.0313/100:0.0313;

try this

its true the graph should be like this..


X(t) signal
