double integral in MATLAB, limits as variable?

Hi, Is it possible to do a double integral in MATLAB numerically, where limits are functions of variables?

Say my integrand is x*y dy * dx
limits are y=0 to 5x
x = 0 to 5

I can manage this by

syms x y
double(int(int(x*y,y,0,5*x),x,0,5))

But, I think, this is clumsy way. This will get worse for triple integrals. Is there any direct function where we can put limits directly with limits even including variables?

fun = @(x,y) x.*y;

xmin = 0;

xmax = 5;

ymin = 0;

ymax = @(x) 5*x;

Q = integral2(fun,xmin,xmax,ymin,ymax,'Method','tiled')
