integralN error with function handles as integration limits

Hi There,

i am trying to solve a 4 fold integral using integralN.m. As soon as i use function handles as integration limits i get the error message:

""""

Error using Untitled>@(v)-sqrt(1.27.^2-v.^2)

Too many input arguments.

""""

wich originates from the execution of the inner integral2-call, according to my findings using the debugger.

How can i use the integralN function with function handles as limits correctly?

Regards

Alex

d = 200;

a = @(x, y, v, w) (cos(atan(sqrt((x-v).^2 + (y-w).^2)./d)).^4)./(d.^2);

xmin=-5;

xmax=5;

ymin=@(x)-sqrt(5.^2-x.^2);

ymax=@(x)sqrt(5.^2-x.^2);

vmin=-1.27;

vmax=1.27;

wmin=@(v)-sqrt(1.27.^2-v.^2);

wmax=@(v)sqrt(1.27.^2-v.^2);

integralN(a, xmin, xmax, ymin, ymax, vmin, vmax,wmin, wmax)

The wmin and wmax arguments must be a function of x, y, and v, even if x and y are ignored.

>> wmin=@(x,y,v)-sqrt(1.27.^2-v.^2);
>> wmax=@(x,y,v)sqrt(1.27.^2-v.^2);
>> integralN(a, xmin, xmax, ymin, ymax, vmin, vmax,wmin, wmax)
