I want double integrate the following
a = 0.3555;
b = 0.3985;
n = 2.343;
f = @(x,y)(1-abs(x/(a*(1-abs(y/b).^n).^(1/n))).^1.745);
integral2(f,-0.3555,0.3985,-0.3555,0.3985)
but it did not work, anybody can help me on this? thanks

The denominator of that is 0 at y = +/- b, which is going to lead to difficulties in integrating. The integral would perhaps be well-defined theoretically if you could well-define what it meant to raise a value to a floating point number.
