syms x; syms y;
k= 2*x+3*y;
f= 4*x+5*y;
m=@(x,y)k.*f;
z=integral2(m,0,2,1,4);

I know a simple solution to this small example, as follows

syms x; syms y;
k= 2*x+3*y;
f= 4*x+5*y;
m=@(x,y) (2*x+3*y).*(4*x+5*y) ;
z=integral2(m,0,2,1,4);

But in my code, the functions k and f are very very long and I want the matlab to do the multiplication and integration directly.

Try matlabFunction

% m=@(x,y)k.*f;
m = matlabFunction(k*f);
