I've been trying to evaluate the following integral using the quad function. My output is completely blank. Not sure why.

 function y = exactintegral(x) 
  y = (1-(x.^3)).*sin(x) + exp((x.^2)/20);
  end

I'm calling it like this:

clear;
Q = quad(@exactintegral,-1,4);

What was Q? I think maybe it is time to start reading the tutorials? I know, real men don't need no steenkin help. The fact that you have a semi-colon after the line where Q is defined, this prevents display of the result. It was still computed though.
