Anything to use instead of TwoD

Anything to use instead of TwoD please, I have this error when I run the simulation:

The error:

   ??? Undefined function or method 'TwoD' for input argument of type 'function_handle'.

k = 2*pi;
z = 1000;

qx = linspace(-200, 200, 501);
qy = linspace(-200, 200, 501);

for ii=1:length(qx)
  for jj=1:length(qy)

        A(ii,jj) = TwoD(@(x, y) (integrand_exact(x, y, qx(ii), qy(jj), z, k)),...
            0, 2*pi, 0, 10, 'Sector', true, 'AbsTol', 1e-5);

    end
end

So if you don't know what TwoD is, why did you type it in? Don't tell me. . . you just snipped out a chunk of someone else's code without really knowing what it requires, how it runs, or what the algorithm is, and just blindly attempted to run that code fragment. If so, why don't you go back to the author or source of your snippet and ask them for it.

It looks like integral2 might fit your needs, although it doesn't have an option called 'Sector'.

Thank you Andrew, I used it just now and I have same error.

[Andrew Newell]

Same error? Do you mean it doesn't recognize integral2? Maybe there is something wrong with your path. Try the following:

which integral2 -all

Does it find integral2? Is there more than one? If you don't find it, try

restoredefaultpath

This will reset your path, and you can then try looking for integral2 again.
