title: Plotting a 3D Function
body: <p>Im trying to plot the following function:
      F(x,y)=Cos(x)*Sin(y)
  With the following features: Labeled all three axes, the x and y axes range from 0 to 2pi with 0.1 spacing, and the viewing angles are orthogonal to any x/y/z=0 plane.</p>
  
  <p>I have the following code</p>
  
  <pre><code>t= 0:0.1:2*pi;
  A=cos(t);
  B=sin(t);
  for i=1:numel(t)
  C(:,i)=A(i).*B(:);
  end
  surf(C);
  xlabel('x axis','fontsize',12)
  ylabel('y axis','fontsize',12)
  zlabel('z axis','fontsize',12)

  </code></pre>
  
  <p>That is almost what I need, for some reason the chart is plotting x and y from 0 to 80, and Im not sure why. I there another way I can try plotting this so that I can use different variables for the cosine and sine inputs?:</p>
