MATLAB: Storage of a loop from negative number

loopnegative numberstorage

How i can storage a loop from negative number For example I have the below loop
for x=-1.5:0.01:1.5
for y=-1.5:0.01:1.5
(x,y)=92.5+(32.53333333)*(x)+(40.12702079)*(y)+(-42.2)*(x^2)+(-34.93538288)*(y^2)+(-3.464203233)*((x)*(y))
end
end
Best regards

xvals=-1.5:0.01:1.5;
yvals=-1.5:0.01:1.5;
for J = 1:length(xvals)
  for K = 1:length(yvals)
    F(J,K)=92.5+(32.53333333)*(xvals(J))+(40.12702079)*(yvals(K)+(-42.2)*(xvals(J)^2)+(-34.93538288)*(yvals(K)^2)+(-3.464203233)*((xvals(J))*(yvals(K)))
  end
end
This can be greatly simplified as:
F = bsxfun(@(x,y) 92.5+(32.53333333)*.(x)+(40.12702079).*(y)+(-42.2).*(x.^2)+(-34.93538288).*(y.^2)+(-3.464203233).*((x).*(y)), (-1.5:0.01:1.5).', -1.5:0.01:1.5);
