I'm self learning matlab and I wanted to plot a graph. I think I have missed an important fact regarding multiplication in matlab. How can I multiply something like the following?
>> x=0:0.01:11;
>> y=(x-1)*(x-2);
Error using *
Inner matrix dimensions must agree.

Use the product .*
x=0:0.01:11;
y=(x-1).*(x-2)

So what's the difference? How do I know when to use ".*" and when to use "*"?
