Integration of two dimensional function

I have a function [[y_1,y_2]]=fun([x_1,x_2]) where x_1,x_2,y_1,y_2 are scalars (the function can be vectorized such that if x_1 and x_2 are k-vectors so are y_1 and y_2). y_i is only dependent on x_i. I am interested in evaluating the integral Y=int(y_1,domain of x_1)+int(y_2,domain of x_2). Can somebody help me find the correct function in Matlab? Many thanks for your help!

q = integral2(fun,xmin,xmax,ymin,ymax) approximates the integral of the function z = fun(x,y) over the planar region xmin ≤ x ≤ xmax and ymin(x) ≤ y ≤ ymax(x).
