How do I fix my x-axis ?

How do I fix the values on my x-axis to go from 0 to 2?

My intention is to plot y=8*cos(2*π*x) and y=8*cos(19*π*x)*exp(-x)

where where x is from 0 to 2 and y is from -8 to 8.

if any one could give me the correct code it would be much appreciated.

hello

here you are :

x = 0:1e-3:2;
y1=8*cos(2*pi*x);
y2=8*cos(19*pi*x).*exp(-x);
figure(1),plot(x,y1,x,y2)

wow! thanks a lot!

you're welcome

btw, is there a way where I can also add a function y=0 (basically i want to insert the x-axis as a line it self to symmetrically split the plot in halves)?

[Mathieu NOE]

sure

you can do it this way :

x = 0:1e-3:2;
y0=zeros(size(x));
y1=8*cos(2*pi*x);
y2=8*cos(19*pi*x).*exp(-x);
figure(1),plot(x,y0,x,y1,x,y2)

thanks a lot!
