I want to integrate numerically f(x,y) with respect to x keeping y constant. Can quad do it with some modifications?
Any other ideas??

y = 5; %eg: y-constant
quad(@(x)f(x,y),xmin,xmax)

you mean to say:
int(int(f(x,y),x,a,b),y,a,b)=dblquad('f(x,y)',a,b,a,b)
valid for all f(x,y)?

Not for *all* f(x,y), but almost certainly for *your* f(x,y). See Fubini's theorem, for example.
