how to draw multicomponent signal in MATLAB?

[W_Heisenberg]

For example,
t = 0:0.01:1;
y = cos(200*pi*t-20*t^2)+cos(4*pi*sin(5*pi*t)+80*pi*t);


then how to draw y?

 

[cherryman]

plot(t,y);

But first, You have to use an array power (.^), because t isn't a matrix.

y = cos(200*pi*t-20*t.^2)+cos(4*pi*sin(5*pi*t)+80*pi*t);

Why you call this signal multicomponent?
