I am trying to plot y=x^2sin(x), where x is from 0 to 2pi. I have defined x using the linspace command, but matlab does not agree with the (x.^2) part. Is there a concept I am missing?

>> x=linspace(0,2*pi);
>> y=(x.^2)*sin(x);
Error using  * 
Inner matrix dimensions must agree.

y= (x.^2).*sin(x.^-1);
