Issue with vectors?

How do I get this to work:

x = 0:.05:1;

y = exp(-2*x)*sin(x*10*pi);

It throws an error, but all I want it to do is give me an equivalent y matrix for my x matrix input. please help.

Sorry to be snarky, but did you trying reading the error message? It tells you what to do right there.

x = 0:.05:1; 
y = exp(-2*x).*sin(x*10*pi);

Note where I used .* instead of just *. (It's not necessary to do that for every instance of *, because in the other places you are simply multiplying by a scalar.)

You might want to take a look at the documentation on Array vs. Matrix Operations for more info.
